The Kepco HSP series provides mission critical power. HSP comprises a group of twelve models, eight 1000 watt power
supplies with outputs from 3.3 volts to 125 volts and four 1500 watt power
supplies with outputs from 24 volts to 125 volts. All models feature
current-sharing for parallel redundant N+1 operation. Models with the or-ing
diode, option R, are capable of hot swapping when plugged into Kepco¹s RA 60
series rack adapter. Models with a digital meter, option M, are also available (see photo, right). A mechanical keying scheme allows the user to define which
power supply will plug into a specified slot in the housing. Output voltage and
current limit settings are adjustable from the panel and may be remotely
with Meter and OR-ing Diodes
The 1000 watt HSP have a wide range a-c input (90-277V a-c). The 1500 watt
models operate from 180-277V a-c mains. Both feature an active power factor
correction (PFC) front end to suppress harmonic generation per EN 60555-2 and
HSP have built-in "or-ing" diodes for redundancy paralleling and a
hot swap" capability. These are indicated by the suffix "R" added to the
Kepco can also provide full service customized DC power distribution systems to match the power supply output(s) with your load(s).

HSP are CE Marked per the Low Voltage Directive (LVD), EN60950 and the EMC Directives, and is compliant with UL 8750, Standard for LED Equipment. See applicable Declaration of Conformity.
This power supply is ideal for applications requiring fault tolerant power systems; see Relevant Technical Articles.
All HSP modules are suitable as DC-DC converters, however note that Safety Agency approvals are valid only for a-c input. DC input voltage ranges for HSP models are as follows:
- 1000W: 125V - 420V d-c
- 1500W: 250V - 420V d-c

Kepco's HSF Series of plug-in power supplies also features current sharing and hot swappablity, in 50 Watt, 100 Watt and 150 Watt power ranges, with outputs from 5V to 48V d-c.
