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.
Applications
The VP-12124 is designed to be used with:
All Valcom page control units
Valcom one-way amplified speaker assemblies
Any application where 24VDC filtered talk battery
is required
