HSP with 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 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 adjusted.

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.

This power supply is ideal for applications requiring fault tolerant power systems; see Relevant Technical Articles.

(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.)
