  • Page 11: Section 2 Unpacking And Installation

    After unpacking the AC Source (unit), carefully conduct a thorough inspection of controls, indicators and chassis. If the unit shows signs of damage, do not attempt to operate. File a damage claim with the carrier responsible. Notify Behlman immediately. 2.2 INSTALLATION WARNING This device must be installed and operated by qualified persons only.
  • Page 12 3 PHASE INPUT POWER REQUIREMENTS The BL5000 series power supplies within the model number range C2 to C6 are designed to be used with a four wire “ Wye” input configuration. Units that are to be supplied with “Delta” inputs above 277 volts require the use of “back-up”...
  • Page 13 INPUT POWER CONSIDERATIONS ( For C8 , C9, and C10 single phase input units ) These models utilize a single phase, full wave, rectifier followed by a capacitive filter to provide main operating voltages. This type of arrangement produces an input current with a high harmonic content. These harmonics contribute to the input current requirement but do not contribute to the output power.

  • Page 15 UNITS WITH T5 OR T5D OPTIONS The diagram below illustrates chassis inter-connection for units provided with the T5 or T5D options. The T5D units are dual range versions of the standard T5 type. As shown below this option includes an additional 7.0 inch high chassis to house the external transformers and range relay for T5D units. Units supplied with T5 options may vary slightly depending on actual customers requirements.
  • Page 16 Installation Considerations This device relies on the proper flow of air to provide internal cooling. Failure to provide this will cause intermittent shut down of the unit due to overheating and will affect the long term reliability. Air is taken into to the unit through “grills”...

  • Page 17: Section 3 Operation

    SECTION 3 OPERATION WARNING This equipment involves the use of voltages and currents that can be hazardous. Only qualified personnel should be allowed to operate or service it. The top cover(s) must always be in place during operation. CONTROLS AND INDICATORS Table 1 lists the controls and indicators used on the different models of the AC Source.

  • Page 20 REMOTE ANALOG CONTROL 3.5.1 REMOTE PRGM CONNECTOR The REMOTE PRGM connector is a nine-pin female “D” connector located on the rear panel. It provides remote analog control of the power source’s amplitude, frequency, output relay, and voltage range (TD option only). A mating nine pin male connector is required for connection.
  • Page 21 OPERATIONAL CONSIDERATIONS GENERAL All BL series incorporate an input rectifier system followed by a capacitive filter. To limit the in rush current to the unit, a soft start circuit is employed. This circuits prevents nuisance tripping of protective circuits in the line circuits as well as reducing stress on internal components .

  • Page 22: Output Noise

    Please note that most line filters are not intended to be used at 400Hz. If the noise level is interfering with low level measurements a linear type AC source should be considered. For more information on linear sources, contact Behlman Sales. T5 & T5D UNITS Adding the external transformer chassis will affect the regulation specifications of the power supply when measured at the transformer secondary.
  • Page 23 T5 &T5D UNITS ( continued ) For the reasons stated above, the output voltmeter accuracy and voltage regulation of these units will be degraded by this option. All specifications apply only when measured at the output terminals of the control chassis.

  • Page 24: Section 4 Maintenance And Adjustments

    THE ABUSES THAT ARE INCLUDED (BUT NOT LIMITED TO) ARE: NOT MAINTAINING THE CLEANLINESS OF THE FILTERS (VACUUMING), OPERATING OUTSIDE THE ALLOWABLE ENVIRONMENT, AND PHYSICALLY DAMAGING THE UNIT. The decision on whether a units warranty is voided will be exclusively reserved for Behlman. ADJUSTMENTS NOTE All the potentiometers used in the procedures that follow are located on the control chassis.
  • Page 25 4.2.2 CONTROLLER CARD POTENTIOMETER ADJUSTMENTS Since certain potentiometer adjustments affect other associated potentiometer settings, a sequence of adjustments must be followed to ensure the proper setting of each potentiometer within the three groups comprising the unit. The three groups: frequency, voltage, and current, are listed below in the sequence to be performed within each group.
  • Page 26 ADJUSTMENTS ( continued ) 4.2.7 VOLTAGE METER ADJUST (R61 on each Phase Control PWA) Set the meter select switch back to phase A and note the phase A output on the DVM. Adjust R61 on the phase A control PWA so that the front panel voltage meter indicates same as the DVM.

  • Page 27: Section 5 Theory Of Operation

    SECTION 5 THEORY OF OPERATION GENERAL 5.1.1 The BL series represents low cost, high performance, AC to AC power invertors. These units provide variable output voltage and frequency from 0 to 135 Vac and 45 to 500 Hz respectively. This series may be operated from a 120/208 Vac, 220/380 Vac 277/480 Vac, 200 Vac (Delta), or 346/600 Vac 2 phase or 120Vac or 240Vac single phase input line at 50 or 60 Hertz.
  • Page 28 CONTROL CHASSIS 5.3.1 The control chassis contains the main power inverters, bias, and control circuitry. The diagram of Figure 1 depicts the basic functional blocks. Note that in the case of the three phase units, only one phase is illustrated as the others are identical.
  • Page 29 Theory of operation (continued) 5.5.4 The output amplitude of each phase is also regulated by the phase control card. A sample of the output voltage is fed to an RMS to DC convertor (U4). The resultant DC voltage is compared to a reference DC voltage set by the front panel voltage control or remote interface.
  • Page 30 THEORY OF OPERATION FOR GPIB \ RS232 INTERFACE All BL series power supplies including the “I” option contain an additional circuit card providing a computer interface. This interface may be one of two standards, IEEE 488 or RS232. This card controls the supply output voltage, frequency , and range as well as providing data back to the controlling computer.
  • Page 31 THEORY OF OPERATION FOR GPIB \ RS232 INTERFACE ( continued ) Read back of output current and voltage is obtained by monitoring the internal circuits of the power source. These dc signals are selected via U1 a two channel “one of four” de-multiplexor. Note that the actual number of channels and inputs used depends on the model of the power source.

    APPENDIX A IGBT DRIVER The insulated gate bipolar transistor (IGBT) driver is a hybrid IC that is used in the over-current detector circuit of each BL5000 unit. Two of these drivers are used in each unit to provide signal isolation, over-current detection, and low-speed over-current cutoff features.

  • Page 42 APPENDIX C BLSERIES AC POWER SUPPLY EIA-232 SERIAL INTERFACE SPECIFICATIONS INTRODUCTION The RS232 interface option for the BL series AC Power Supplies allows two way communication with most computer systems. All programmable setup parameters may be queried or modified via the RS232 interface using command syntax described below. EIA-232 INTERFACE UTILIZATION The RS232 interface may be connected to modems, controllers, computers, or any other equipment capable of communicating with the RS232 protocol.
  • Page 43 EIA-232 SERIAL COMMUNICATION The BL Series Power Supply incorporates an EIA-232 serial communications interface, which allows all function to be programmed and monitored remotely via a host computer. The Power Supply receives ASCII encoded command strings via a EIA-232 interface according to MATE System Control Interface Standard No. 2806763 (IEEE-716 CIIL).
  • Page 44 CIIL COMMANDS EXPLANATION -ALL SET, SRX,SRN commands are part of the setup command above. SET VOLT <value> Sets output voltage to given value, in volts rms. The following values are permitted: 0 < value < 135, or 270, dependent on range selected and type of unit. If set volt (value) not received, then use SRN VOLT (value), or SRX VOLT (value).
  • Page 45 Notes Delay is necessary after issuing a setup command, due to the output voltage slew of 100v per 500ms. On dual range Power Supplies, this command selects the LO or HI voltage range. Dual Ranges are 0-135 volts and 0-135/0-270 volt. If this command is omitted from the setup string the unit will default to the lowest available range.
