MISCELLANEOUS FEATURES 1.4.1 CONTROL/PROGRAMMING VOLTAGE CHANNEL: Output voltage is controlled continuously throughout the specified adjustment range via a 10-turn potentiometer mounted behind the front panel. External control can be exercised either by resistance or by control voltage (see PAR’s. 3.3 and 3.4). CURRENT CHANNEL: Output current is controlled continuously throughout the specified adjustment range via a 10-turn potentiometer mounted behind the front panel. -

1. THE POWER SUPPLY WILL NOT OPERATE UNLESS THE REMOTE SENSE LINES ARE PROPERLY CONNECTED TO THE OUTPUT TERMINALS! Connect the remote sense ter- minals to the output bus bars using the mating I/O Connector (Kepco P/N 142-0422) or other means as shown in PAR. 2.7.5.1 and Figure 2-4. -
Page 18: Installation
• When used as part of a plug-in power system, refer to the Instruction Manual accom- panying the applicable Kepco rack adapter for installation directions. For all installations, provide adequate clearance around air inlet and exhaust locations and ensure that the temperature immediately surrounding the unit and especially near the air inlets does not exceed the maximum specified ambient temperature for the operating conditions. -

3-wire safety line cord via a polarized mating plug. Kepco offers as accessories (see Table 1-3) both a user-wired mating connector and a prewired linecord set, the latter configured for North American applications. Terminal assignment follows internationally accepted conventions (see Figure 2-3). -
Page 20: Power Supply/Load Interface
The use of the proper fastener size and inclusion of a lockwasher are critical to maintaining intimate contact between the load conductor and output bus bar; Kepco recom- mends the use of fasteners made of conductive material (brass, phosphor bronze, etc.) to enhance conductivity;... -
Page 21: Load Connection - Method I (Local Error Sensing)
2.7.5.1 LOAD CONNECTION - METHOD I (LOCAL ERROR SENSING) The most basic power supply/load interface is a 2-wire connection between the power supply output terminals and the load. This connection method employs local error sensing which con- sists of connecting the error sense leads directly to the power supply's output terminals. Its main virtue is simplicity: since voltage regulation is maintained at the power supply output, the regula- tion loop is essentially unaffected by the impedances presented by the load interconnection scheme. -
Page 22: Load Connection - Method Ii (Remote Error Sensing)
2.7.5.2 LOAD CONNECTION - METHOD II (REMOTE ERROR SENSING) If the load is located at a distance from the power supply terminals, or if reactive and/or modu- lated loads are present, remote error sensing should be used to minimize their effect on the volt- age stabilization. -
Page 23: Load Connection - Method Iii (Series Connection)
2.7.5.3 LOAD CONNECTION - METHOD III (SERIES CONNECTION) Units may be connected in series to obtain higher output voltages. Each power supply in the series should be protected by a clamping diode connected in its non-conducting direction in par- allel with the output; this diode protects the power supply outputs against secondary effects in the event of a load short. -
Page 24: Load Connection - Method Iv (Parallel Operation)
2.7.5.4 LOAD CONNECTION - METHOD IV (PARALLEL OPERATION) Identical HSP power supply models may be connected in parallel in order to provided increased output current to a common load (see Figure 2-7). This permits the user to obtain significantly higher load ratings than for a single HSP power supply. The number of power supplies required is determined by dividing the required load current by the current rating of the applicable HSP model, and rounding up to the next whole number when necessary. -
Page 25: Load Sharing
When operating power supplies in hot-swap applications, the use of an output blocking diode is mandatory to prevent excessive output transients and power connector damage due to arcing at the output terminals. In applications where redundancy is required but hot-swapping is not, the blocking diode is beneficial in that it adds a layer of isolation between each power supply output and the common d-c bus, protecting the bus against the possibility of a short at the power sup- ply output. -

HSP series plug-in rack adapters. RETAINING LATCHES HSP series power supplies are provided with (2) retention latches located at each side of the bottom edge of the front panel (see Figure 2-1). These latches work in conjunction with the HSP series plug-in rack adapters to prevent unauthorized or inadvertent module extraction from an operating power system. -

The second location is the I/O connector: here, the test points are labeled VSET and ISET, and are available at pins 36 and 33, respectively, with circuit return accessed at pin 19 (-S) (see Figure 2-3). -

The signal generated by the OVP detector is gated with a signal from the fault detector circuit to produce a selective overvoltage shutdown function which prevents shutdown of operational power supplies in a parallel-redundant power system configuration. The OVP latches of any working power supplies are disabled, allowing only the faulty modules to be latched off;... -
Page 32: Current Walk-In Circuit
3.10 CURRENT WALK-IN CIRCUIT HSP power supplies incorporate a specialized output regulator start-up circuit for applications involving use of the HSP as a battery charger. This circuit, enabled via switch S1-2, overrides the normal duty-cycle-based soft-start circuit, which could still result in very fast output current rise rates into a discharged battery, and substitutes a controlled-current rise circuit with a time constant in accordance with Bellcore TR-TSY-000947 requirements for telecommunications bat- tery rectifiers (see Figure 3-4). -
Page 33: Remote Inhibit/Remote Reset Controls
3.12 REMOTE INHIBIT/REMOTE RESET CONTROLS HSP power supplies incorporate two TTL-level inputs, RC1 and RC2, accessed via the I/O con- nector, which can be used to disable the output regulator via external stimulus. These two con- trols operate from an internal 5V supply (5VAUX) which is isolated from both input and output (see PAR. -

The voltage level of this signal is generated with respect to the negative sense return (pin 19). 3.14 STATUS INDICATORS AND STATUS FLAGS HSP power supplies provide both visual and electrical indication of the status of various critical functions including source power status, output status, fan status and overtemperature condi- tion;... -

These signals indicate a fault condition until the bulk voltage is greater than 390V d-c. Once the bulk voltage reaches 390V d-c (indicating that the PFC boost converter is operating and assuring that full ride-through time is available at rated load) these signals revert to “normal”... -

3.15 FRONT PANEL METER (M OPTION) OPERATION HSP series power supplies are available with a meter option (‘M' suffix) which incorporates a 3½ digit LED meter display on the front panel. The meter provides both voltmeter and ammeter functions. The V-A rocker switch directly below the meter (Figure 3-7) selects either output volt- age (V) or module current (A) as the normally-displayed parameter. -
