SPS-510

10A/5A Switching Power Supplies with Charger

12/24 VDC Selectable Output

The SPS-5 and SPS-10 are part of our SPS-510 Series Linear performance power supplies. They are clean, efficient, heavy duty, low frequency off line switching power supplies with battery charger and power supervision. Even though the wattage is the same for both the SPS-5 5A at 24 VDC and the SPS-10 10A at 12 VDC, we offer separate 12V and 24V models for optimum performance.

The SPS-510 series use a very low switching frequency of 23KHz, just above our hearing range. This, coupled with extensive filtering, provides a balance of super clean power. This design eliminates interference problems with proximity readers and can be used wherever a linear power supply is required. The universal AC input works all over the world. The SPS-510’s become an uninterruptible power supply when a stand-by battery(s) is connected with the supplied cable. 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 any capacity between 4 and 400A hours. The SPS-5 24 VDC is rated for 4A continuous current with 1A reserved for battery charging while the SPS-10 12 VDC is rated for 8A continuous current with 2A of current for battery charging.

Power Supervision includes a battery(s) disconnect relay to prevent deep discharge and a separate power trouble alarm relay. The power trouble alarm relay output, form C contacts, can be used to signal a buzzer and/or other signaling device. Both relays are normally energized for fail-safe operation. The trouble relay has a green LED that is on when power is good. The relay will drop off of normal when the standby battery(s) reaches about 70% of capacity. This low voltage indication represents low battery and/or AC power failure. High voltage or over heated failure will also indicate power trouble.

A Service Switch (not on CE models). Switch allows the DC output to be turned off for service.
