CHARACTERISTIC REQUIREMENT
SIGNAL AND CONTROL
Remote Error Sensing
3.3V & 5V Models 0.25V per wire
All other Models 0.8V per wire
Remote On/Off Control
Isolated TTL-compatible signal; either logic
high or logic low will disable output.
Load Sharing
Within 5% of load when connected via load
sharing wire (see PAR. 2.7.6).
Load Monitor
0-5V analog signal proportional to output
load current; 5V at 100% of rated load.
Status Flags
(Form C dry relay contacts)
(See PAR. 3.14.)
(See Notes 5 and 7.)
POWER
Indicates low source
voltage; signal
asserted a minimum of
5 msec prior to loss of
output voltage.
OUTPUT
Indicates HSM Power
Supply in normal
operating mode.
OVERTEMP
Indicates HSM Power
Supply in
overtemperature
shutdown.
FAN FAIL
Indicates failure of
internal cooling fan.
Auxiliary Voltage
(Isolated)
4.75-5.25V d-c output, 0 - 100mA,
parallelable, output isolated (500 V d-c),
Input isolated (SELV) (See Operating
Instructions, PAR. 3.11).
Voltage Set Programming
Mode selected by
internal switches
(See Note 6.)
(See PAR. 3.3.)

Cooling
Internal d-c fan (inlet, exhaust as indicated in
Figure 1-3).

PHYSICAL
Dimensions See Figure 1-3.
Weight 16 lbs. (7.3Kg)
Source Connections
3-pin power entry module (compatible with IEC
320/C19 molded line cord plug.
Load Connection
Two bus bars (+ and -)1.0 x 0.125 inch, copper
w/bright nickel finish
Signal Connection 37-pin D-subminiature connector (male)
NOTES 5: Status flags are isolated and operate independently.
6: The POWER/DCFAIL fault detector window tracks pro-
grammed output voltage, however, the overvoltage protection
trip point remains unaffected.
7. Form C contacts: rated from 30V d-c/1A to 60V d-c/0.3A.
