Kepco Inc. DC Power Supply: 28V/53A/1500W Din Rail Mountable, Hot Swap; w/ Digital LED Meter option
The Kepco HSP series comprises a group of ten models, seven 1000 watt power supplies with outputs from 3.3 volts to 48 volts and three 1500 watt power supplies with outputs from 24 volts to 48 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 Kepco's 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 adjusted.
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 EN 61000-3-2.
Kepco can also provide full service customized DC power distribution systems to match the power supply output(s) with your load(s).
HSP have optional built-in "or-ing" diodes for redundancy paralleling and a hot swap" capability. These are specified by appending the suffix "R" to the model number.
HSP Rear View HSP are CE Marked per the Low Voltage Directive (LVD), EN60950 and the EMC Directives. 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 newly introduced 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.)
