1. INTRODUCTION
1.1 SCOPE OF MANUAL
This Operator's Manual covers the installation and operation of the Kepco HSF A and HSF AM
300W Series of Switching Power Supplies. Basic models are identified by the suffix “A” following
the model number; models with the suffix “AM” include an integral voltage/current meter. For service information, write directly to: Kepco Inc., 131-38 Sanford Avenue, Flushing, New York,
11355, U.S.A. Please state Model Designation and Serial Number of your HSF Power Supply.
This information can be found on the nameplate of the unit.
1.2 DESCRIPTION
The Kepco HSF A and AM 300 Watt Series are hot swappable, high frequency switching, plug-in
power supplies that are completely interchangeable with the metered HSF AM Series, as well as
with Kepco’s earlier 300 Watt HSF Series (non A). When integrating A and non A models refer to
PAR’s. 3.5 and 3.7.2.2 regarding isolation of the return signal of the RC and PF features. Unless
otherwise noted, all data supplied herein for A models applies to AM models as well.
Six models may be selected for outputs of 5V, 12V, 15V, 24V, 28V or 48V. They employ forward
conversion and power factor correction and are designed to operate in a fault tolerant power system. Input voltage range is single phase 85-265V a-c (47-63Hz) or 120-330V d-c. Input voltage
which is out of specification may cause unit damage. Safety standards apply when input voltage is
within 100-240V a-c (50-60Hz). A built-in current balancing circuit and OR-ing diodes allow configuration for hot-swap and parallel-redundant N+1 operation.
HSF A (without meter) and AM Models (with meter) use the HSF output to power the VDC ON
indicator and internal alarm relay. A minimum HSF output voltage is needed to maintain functionality for these components. For HSF AM models a minimum output is also needed to power the
meter. Model HSF 5-60AM is the exception, requiring no minimum output to power the internal
relay and meter, and a minimum output of around 3V d-c to power the VDC ON/ALARM indicator.
These power supplies are designed to be used with Kepco's Series RA 19-4C rack adapters. The
RA 19-4C rack adapter accepts up to four 300W modules. All input/output connections are
through a 24-pin connector that plugs in to the rack adapter. All external connections described in
the following paragraphs are made through the rack adapter’s I/O connector (see Figure 1).

(1) To adjust output voltage down to approximately 0V requires that DIP SW1, position 7 be set to ON. Refer to Table 5 for mini-
mum conditions required to maintain proper operation of alarm relay, meter (AM Models only) and VDC ON/ALARM indicator.
(2) Using trimpot to attain voltages outside the specified adjustment range may trigger overvoltage (PAR 3.6.1) faults. Recovery
is by removing, and after approximately 40 seconds, reapplying AC input power or by reset (open and close) at ±RC termi-
nals (no delay).
(3) See Figure 2 for power derating.
(4) Square type. Output voltage returns automatically when cause is removed. (see PAR. 3.6.2).
(5) CAUTION: The unit may be damaged if operated under overcurrent or shorted conditions for more than 30 seconds.
(6) When overvoltage is detected, output is shut OFF. Recovery is by removing, and after approximately 40 seconds, reapplying
AC input power or by reset (open and close) at ±RC terminals (no delay).
(7) Ripple and noise levels above are satisfied when conditions are 0 to 100% load, 0 to 50°C (load is derated from 50 to 70°C,
see Figure 2), and bandwidth ≤ 100MHz.
