HSF-1UR
150W SERIES
KEPCO SINGLE OUTPUT, 1U SIZE, 150 WATT
HOT SWAP PLUG-IN POWER SUPPLIES
I — INTRODUCTION
The Kepco HSF-1UR 150 Watt Series hot swappable, high
frequency switching, plug-in power supplies with built-in
power factor correction (PFC) employ forward conversion
and are designed to operate in a fault tolerant power sys-
tem with either a-c or d-c input. A thermistor soft-start cir-
cuit limits start-up surge; an input fuse (5A, 250V) protects
against shorts. Built-in OR-ing diodes (all models) and a
forced current share circuit (all models except 3.3V) allow
configuration of all models for hot-swap and parallel-redun-
dant N+1 operation.
The heart of the HSF-1UR Series is a Kepco RTW power
supply allowing them to weigh less and have improved effi-
ciency (input current) specifications over the older HSF-1U
Series. There are three options available: C, X and Y. Fea-
tures for all models are the same except as follows: C
option (-1URC) models include a current sensing resistor,
allowing external current monitoring within ±10% (contact
Kepco if greater accuracy required). X option (-1URX) mod-
els have remote control, the ability to turn the unit on and
off from a remote location. Y option models (-1URY)
include both current monitoring and remote on-off capabili-
ties.
These power supplies are designed to be used with
Kepco’s Series RA 19-1U rack adapters. The RA 19-1U
rack adapter accepts up to four 50-, 100- or 150-Watt units
(see Figure 1). All input/output connections are through a
24-pin connector that plugs in to the rack adapter. All exter-
nal connections are made through the rack adapter (refer
to the RA 19-1U manual which is available for free down-
load at:
www.kepcopower.com/support/opmanls.htm#ra19-1u
Seven models may be selected for outputs of 3.3, 5, 12, 15,
24, 28 or 48V (see Table 1).
When the input is cut off, the output is maintained for 20
milliseconds minimum. If the power supply shuts down due
to an output overvoltage condition, it is then necessary to
wait 60 seconds minimum before turning the unit on again.
EMI filtering is designed to meet FCC Class B rating and
VDE 0871 Class B rating. Table 1 contains specifications
that vary for each model of the HSF-1UR 150 Watt Series.
Common specifications are listed on page 4.

(1) Overtemperature or overvoltage shuts down the output. Recover by recy-
cling a-c input (30 second delay required before resetting).
(2) 25°C, Nominal. Input.
(3) Hiccup mode operation. After the cause of overcurrent is removed, output
voltage recovers automatically.
(4) See power rating curve, Figure 4. Exceeding maximum power rating may
result in oscillation or a drop in output current or voltage.
(5) Ripple and noise will be approximately 1.5 times higher in the operating temperature
range -10 to 0°C.
(6) Sense resistor included on C and Y Models only (see “Current Monitor” on page 2 for
details).
(7) Peak current and thermal protection applicable to 24V model only. See Figure 1 for
peak power requirements.
