SCOPE OF MANUAL
This Operator's Manual covers the installation and operation of the Kepco HSF A and HSF AM
600W 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 ser-
vice 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.

DESCRIPTION
The Kepco HSF A and AM 600 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 600 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.
Five models may be selected for outputs of 12V, 15V, 24V, 28V or 48V. They employ forward con-
version 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 (with meter) Models use the HSF output to power the VDC ON
indicator and internal alarm relay. A minimum HSF output voltage is needed to maintain function-
ality for these components. For HSF AM models a minimum output is also needed to power the
meter.
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 600W 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).
