VP-4024C
-24 VOLT DC POWER SUPPLY
INTRODUCTION
These instructions provide the specifications, installation and
maintenance information for the VP-4024C, -24 Volt Power Supply.
SPECIFICATIONS
The VP-4024C is a fully regulated -24VDC, 4 Amp power supply.
The primary is protected by a 2 Amp 5x20 mm fuse. The output is
floating with respect to ground, and the two outputs may be
connected together for one 4 Amp output. The regulator will
maintain -24 Volts
±
2.5 Volts over the rated range of input voltages
and output loads. A greater than 4 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.
“WARNING: To reduce the risk of fire or electric shock, do not expose
to rain or moisture.”
“WARNING: Shock hazard – Do Not Open.”
“AVIS: Risque de choc Electrique ne pas Ouvrir.”
“PELIGRO: Corriente Electrica – No Abres.”
CAUTION: For continued protection against risk of fire, replace only
with 2A, 125V SLO-BLO type fuse 5x20 mm, UL Listed.
