HSP-A power supplies for such applications as battery chargers. The HSP-A power supply is specifically designed for use in Kepco RA 90 or similar plug-in rack adapters as a hot replaceable module in a redundant power system. Forced current sharing and internal output blocking diodes enhance power system reliability. -

These latches work in conjunction with the HSP-A series plug-in rack adapters to prevent unauthorized or inadvertent module extraction from an operating power system. -

Page 27: Output Voltage Programming
OUTPUT VOLTAGE PROGRAMMING HSP-A power supplies provide three different methods for programming the output voltage reg- ulation point: internal (see PAR. 3.3.1), external resistance (see PAR. 3.3.2) and external volt- age (see PAR. 3.3.3). When using either internal or external resistance programming, the minimum programmable voltage is 16.6-20% of nominal, while external voltage programming permits adjustment down to zero. -
Page 28: External Voltage Programming
(0-10V) connected between pins 18 and 19 (VPROG, -S) of the correspond- ing I/O connector on the rack adapter (see Figure 3-3). This technique is useful when implementing digital control of the power supply output voltage via a D/A converter; Kepco's SN/ SNR 488 programmers are ideally suited to these requirements. -
Page 29: Internal Current Limit Programming
(0-10V) connected between pins 15 and 19 (IPROG, -S) of the I/O connector (see Figure 3-4). This technique is useful when implementing digital control of the power supply current limit via a D/A converter; Kepco's SN/SNR 488 programmers are ide- ally suited to these requirements. -
Page 30: Internal Temperature Monitoring (Option T Or Mt)
INTERNAL TEMPERATURE MONITORING (OPTION T OR MT) Both Option T and MT allow monitoring of internal unit temperature via a status signal that is proportional to internal temperature: When option T or MT is installed, an internal thermal sen- sor provides an output voltage proportional to internal temperature between 0V (0°C) and 10V (100°C ±2°C) at the ratio of 0.1V/°C. -
Page 31: Overvoltage Protection Adjustment
FIGURE 3-6. VOLTAGE AND CURRENT SETPOINT MONITORS Measurement quantities are defined as follows: , VSET: This voltage represents 1/10 (1/100 for 125V models) of the programmed output voltage. As an example, VSET (or V ) = 4.63V corresponds to a programmed out- put voltage of 46.3V ±1%. -
Page 32: Ovp Adjustment Setup
3. With source power removed, connect load as shown in Figure 3-7 for local sensing and con- nect a 20k ohm potentiometer between pin 37 and the output bus bar; adjust the pot for min- imum resistance. 4. Rotate OVP ADJUST control on HSP-A fully clockwise. 5. -
Page 33: Ovp Retrigger/Retrigger Lockout
NOTE: The overvoltage protection circuit senses the voltage directly at the output terminals of the power supply, not at the error sensing point. When selecting an overvoltage set point, the user must take into account the expected power lead voltage drop and, if applicable, the transient response overshoot in order to avoid false shutdowns. -
Page 34: Undervoltage Lockout
3.11.2 UNDERVOLTAGE LOCKOUT Undervoltage lockout mode is enabled when S1-3 is set to ON (Figure 2-2). The crossover from voltage- to current-mode operation is the same as for Continuous Limiting. However, after approximately 15 seconds, the output load regulation circuit is locked off via the overvoltage protection latch, requiring the user to recycle source power to restart the power supply (see PAR. -
Page 35: 5Vaux Floating Supply
3.13 5VAUX FLOATING SUPPLY HSP-A power supplies are equipped with an internal auxiliary supply which provides 5V at loads up to 100mA. It is derived from the internal cooling fan supply and is, therefore, present when- ever the source power is within specification and the internal bias supply is operating, regard- less of the status of the output regulator. -
Page 36: Module Current Monitor
These two signal levels are TTL-compatible, both for voltage levels and source/sink capability. If not actively driven, these signals have no effect on power supply operation. Activation of either one of these control lines results in an immediate shutdown of the output PWM regulator, includ- ing reset of the soft-start, undervoltage, and current walk-in circuits. -

Page 38: Timing Diagram For Power And Dcfail Status
FIGURE 3-10. TIMING DIAGRAM FOR POWER AND DCFAIL STATUS Table 3-3 provides an operating matrix of the DCFAIL status function; see Figure 3-10 for timing relationships. The output voltage fault limits are ±5% of programmed output voltage, while the undercurrent fault limit is <70% of required module current; signal reset requires output voltage recovery to within the specified ±1% regulation range and/or module current recovery to >85% of required module current, respectively. -
Page 39: Overtemp Indicator And Status Flags
3.17 FRONT PANEL METER OPERATION HSP-A series power supplies incorporate 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 2-1) selects either output voltage (V) or module current (A) as the normally-dis- played parameter. -
Page 40: Ammeter Operation
3.17.2 AMMETER OPERATION With the V-A selector switch set to ‘A' position (amber A indicator illuminated), the meter nor- mally displays the actual output current (within ±3%) presently being supplied by the module. If the ACTUAL/SETPOINTS switch is depressed with the V-A selector switch set to I, the display shows the programmed current limit (±1%) of that module, regardless of the actual current being supplied at the time (ref. -

Page 42: Verify Power Supply Output Voltages Set Correctly
3.19.1 VERIFY POWER SUPPLY OUTPUT VOLTAGES SET CORRECTLY. Set the front panel meter V/A switch to V position and press the momentary SETPOINTS switch. The meter displays the voltage set point of the unit. Repeat for each unit in the parallel combination. - Page 43 To accomplish the above without using the meter, the current delivered by each unit can be cal- culated by measuring the IMON signal at pin 32 of the I/O connector referenced to pin 19 (S–). IMON is a 0 to 5V signal representing 0 to 100% of the rated output current of the unit. E.g., for the HSP 12-84A, IMON of 3V represents 60% or 84A, or 50.4A.
