VP-12124

24 VOLT DC SWITCHING POWER SUPPLY

INTRODUCTION

These instructions provide the specifications,

installation and maintenance information for the

VP-12124 24 Volt Power Supply.

SPECIFICATIONS

The VP-12124 is a fully regulated 24VDC, 12 Amp

switching power supply. The primary is protected by a

6.3 Amp fuse and the six, 2 amp outputs by

auto-resetting fuses. The outputs are floating with

respect to ground. The regulator will maintain 24

Volts +/-2% over the rated range of input voltages and

output loads. A greater than 12 Amp load on power

up will cause the power supply to current limit. Short

circuit protection is provided. Over voltage is provided

to limit the output voltage to approximately 28 Volts

should a failure occur within the power supply.

Outputs may be paralleled but not series connected.
