SPS-6.5/SPS-3.3 Module

The SPS-3.3 and SPS-6.5 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-3.3 (24V) and the SPS-6.5 (12V) are both 100 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.  To tolerate brownouts, the SPS-6.5 and SPS-3.3 will remain operational down to 60vac.  The SPS-3.3 and SPS-6.5 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-3.3 and SPS-6.5 become an uninterruptible power supply when a stand-by battery(s) is connected with the provided battery cable.  These supplies have a special power limiting circuit that allows the battery(s) 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 any capacity between 4 and 40 Amp hours.  The SPS-3.3 24VDC is rated for 3 Amps continuous current while the SPS-6.5 12VDC is rated for 6 Amps continuous current.  The SPS-3.3 24VDC has 300ma reserved for battery charging, while the SPS-6.5 has 500ma reserved.  The PDM-8C (C8 option) distribution board adds 8 class II power limited outputs. Power Supervision uses 3 relays and electronics to indicate 3 levels of the stand by battery(s).  The AC FAIL relay is triggered by detecting a small drop in DC output 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 a form C contact set 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 3^rd relay with electronics is used to disconnect the battery(s) at the end of its service limit, preventing deep discharge that can damage the battery(s).  All three relays are normally energized for fail safe operation.
