SPS-6

5A/3A Switching Power Supplies with Charger

12/24 VDC Selectable Output

The SP & SPS-6B are heavy duty self contained, efficient, clean, off-line switching power supplies that are slide switch selectable between 12 VDC at 5 A, and 24 VDC at 3 A.  Both have a precision lead acid battery(s) charger that obtains maximum battery life while providing a clean 12 VDC or 24 VDC uninterruptible power supply for access control security systems.  The universal AC input allows these power supplies to be powered anywhere in the world without any alteration.  The SP & SPS-6B have exceptional brown out capability with operation down to 60 VAC.  The SP & SPS-6B have an extensive filtering system that provides a very clean output that can power most readers and sensitive equipment.  Each is electronically protected against Battery(s) reversal, shorting or overloading.  The DC outputs are all class II power limited, and thermally protected.  Each of these protective features will self-restore.

Before connecting load and battery(s), slide 12v/24v selector switch to desired voltage.  Caution, damage can occur when switched with DC output load.  Confirm proper voltage before connecting devices.

The SPS-6B is UL Listed and has the additional supervisory features of a Battery disconnect relay that disconnects the battery(s) when they are depleted preventing deep discharge.  Also there is a set of form “C” relay contacts that indicates AC power failure and another set of form “C” relay contacts to indicate low battery(s).  Depending on load, low battery trouble Indicates about 70% battery capacity remaining.
