SPS-3.6M2E with 7AH Battery

SPS-3.6M2 / SPS-2.2M2 Module

The SPS-2M2 and SPS-3.6M2 are part of our SPS-36 Series Linear performance power supplies.  They are clean, efficient, heavy duty, low frequency off line switching power supplies with precision battery charger and power supervision.  These supplies are so clean that they can be used anywhere a linear or switching supply is recommended.  The filtering and switching systems we use are very similar to what you would find on high quality computers.  Even though the SPS-2M2 (24V) and the SPS-3.6M2 (12V) are both 50 watt power supplies utilizing the same printed wiring board, we offer separate 12V and 24V models for optimum performance.  The universal input of 85vac to 260vac allows them to be used anywhere in the world without adjustments to the power input.  The ability to run at very low AC voltages allows the SPS-2M2 and SPS-3.6M2 to tolerate brownouts very well.  The SPS-2M2 and SPS-3.6M2 are fully self-contained and isolated  from the line to all world safety standards.  Each power supply weighs less than 1.5 lbs and occupies less than ½ of a cubic foot of cabinet space.

The SPS-2M2 and SPS-3.6M2 become an uninterruptible power supply when a stand by battery(s) is connected with the battery cable provided.  These supplies have a special power limiting circuit that allows the batteries to be float charged across the output without lock up or chirping on and off.  The battery(s) is protected with an automatic resetting circuit breaker and diode for over current and accidental reversed battery hookup.  Precision float charging means faster recovery time and longer life for the battery(s).  There is no switch over or voltage drop when input power fails.  Standby battery(s) can be of any capacity between 4 and 100 Amp hours. The SPS-2M2 24VDC is rated for 1.7 Amps of continuous

current, while the SPS-3.6M2 12VDC is rated for 3.3 Amps continuous current.  Power Supervision uses 3 relays and electronics to indicate 3 levels of the stand by battery(s).  The AC FAIL relay detects a small drop in DC voltage and provides a form C contact set to indicate the AC has failed and the supply is running on Standby Batteries.  The LOW Bat relay provides form C contacts to indicate the battery(s) is low.  Either of these form C contacts can be used to signal a buzzer and/or other signaling device.  A 3rd relay with electronics is used to disconnect the battery from the Power Supply and Load at the end of its service limit, preventing deep discharge that will damage the battery(s).  All three relays are normally energized for fail safe operation.
