Redundant Output
The RSPS-30 is a 19" rack mounted power supply system featuring a redundant 12V DC output. The APS (automatic power selector) is located in the center of the rack mount and constantly monitors the DC output voltage. When the APS senses a primary power supply drop out, it will automatically switch over to the secondary power supply. A 6 foot power cable is included for simple connection to your equipment.

Voltage Output
The primary power supply’s output voltage is set at the factory to 14.1 VDC. The secondary or back up supply’s output is fixed at 13.85 VDC. When the APS senses a voltage drop on the main supply, it will automatically switch over to the secondary power supply for continuous operation. Once the primary power supply voltage resumes back to its normal output, the APS will automatically switch back to the primary power supply. PLEASE NOTE: for proper operation a minimum of 0.5 V separation is required between the primary and secondary power supply voltage outputs.

Mount the 19" Redundant power supply system and secure with (4) rack mount screws. Connect the supplied DC output cord to your equipment. Please add a 30A fuse/holder to the DC output cord and make sure you have good air flow to both power supplies. Plug in both AC power cords to a reliable AC wall outlet. To ensure proper operation, turn on the AC power switch located on the front of each power supply and each front mounted switch should illuminate.

With both power supplies on, the system should be operating normally. Now switch OFF the primary power supply’s front mounted switch and the secondary power supply should now be powering the system. After one minute, turn ON the primary power supply front mounted switch and the system should once again operate normally.

Installation Instructions

  1. Unplug the power supply from the mains supply outlet.
  2. Select the correct input voltage (See Input Voltage Selection).
  3. Connect the power cable’s positive (red) wire to the positive terminal and connect the negative (black) wire to the negative terminal on the back of the power supply or use the Powerpole connectors mounted on the front panel.
  4. Plug the power cable into the power socket on the back of the radio.
  5. Plug the power supply into the mains supply outlet.

Turning the power supply on
Turn the power supply on by pressing the power switch to the 'ON' Position.

Turning the power supply off
Before you turn the power supply off, turn the radio off as described in the user documentation for the radio. Then turn the power supply off by pressing the power switch to the 'OFF' Position.

The RSPS-30 power supply is cooled by convection and forced air cooling (normal airflow around the power supply in combination with a temperature controlled fan to improve cooling at higher levels of use). The fan is activated by a sensor when the temperature rises above 70°C.
