    SECTION 2 | Description & Applications Fuse Replacement Ensure properly rated fuse (250V, 4A) is used in each of the modules. Environment DO NOT expose power supply to rain, snow or water spray Dis-assembly And Repair The power supply should be disassembled or repaired by a qualified technician. Incor- rect reassembly or repair may result in a risk of electric shock or fire which may result in personal injury and property damage.

    SECTION 5 | Front Panel Controls & Indicators The following controls and indicators are provided on the front panel : 1. A. Power ON/OFF Switch – The rocker switch will illuminate when switched ON. B. Breaker – A 25A circuit breaker provides protection on the input side against overload. 2.
  • Page 9 SECTION 6 | Rear Panel Connectors Remote Monitoring And Signalling A provision has been made for remote signaling and monitoring of the following operational conditions and parameters: 1. Operational status of the 5 power supply modules (PSM) 2. Failure condition of the cooling fan(s) 3.

    The “PSM Status” LEDs will, however, remain illuminated, but dimmed. When the overload reaches approximately 70A for SEC-2450BRM or 56A for SEC-2440BRM or 42A for SEC-2430BRM (the output voltage will be approximately 5.4V), the unit will shut down (will enter hiccup mode).

    SECTION 8 | Installation & Operation Switch ON the unit by pressing the power ON/OFF switch to ON position. The switch will be illuminated confirming that input power is available. A short beep may be generated by the temperature fault alarm circuit on powering ON the unit .
  • Page 12 SECTION 9 | Operation of Battery Back-up The voltage at the output terminals load + and load – will be as follows : At no external load approx. 27.8V At 10A load approx. 27.6V At loads > 10A approx. 27.6V minus 5mv per amp above 10A When there is a requirement of un-interrupted D.C.

  • Page 13: Output Voltage Adjustment

    SECTION 9 | Operation of Battery Back-up Availability of AC power is signaled for remote monitoring through an opto-coupled signal through the d-sub connector (see page 9 under “Remote Monitoring & SignalI- ing”). This signal may also be used to indicate that the load is being powered by battery (in case external battery is used for battery back-up).
  • Page 14 SECTION 10 | Output Voltage Adjustment ode D1) is tightly regulated at the preset value of 28V +/-1%, The voltage at the output terminals load + and load - will vary between 27.8V at no load to 27.45V at full load of 50A due to the forward voltage drop of the isolating Schottky Diodes D1 and the drop along the DC bus and wiring.

  • Page 15: Installation & Removal Of Modules

    Additional optional module(s) (Model No. SEC-1024MPSB) can be added to upgrade the output current capacity of SEC-2430BRM / SEC-2440BRM by steps of 10A to a maximum of 50A. For example, SEC-2430BRM (30A) can be upgraded to SEC-2440BRM (40A) by adding 1 additional optional 10A module (SEC-1024MPSB) or to SEC-2450BRM (50A) by adding 2 additional optional 10A modules (SEC-1024MPSB).

  • Page 18 SECTION 13 | Limiting Electromagnetic Interference (EMI) 1. Switched mode power supplies (SMPS) employ high frequency switching and thus, are a source of radio interference, a recipient of radio interference and a conduit of radio interference (older linear type transformer based power supplies do not employ high frequency switching voltages and will be quieter as compared to switching type of supplies ).
