    Important safety instructions please read before using your power supply. Caution ! All electrical installations must meet local and na- tional wiring codes and should be performed by a quali- fied electrician . Operation of cooling fan the heat produced is extracted by forced air cooling. In case a...

    Load and battery connections the load & battery terminals on the power supply have a tubu- lar hole of diameter 8mm (0.31”) with a set screw. Always ensure that the connections are secure and the screws are tightened properly. Loosely tightened connections result in excessive voltage drop and may ca...

    Description this is a 19 inch, 2u height (3.5”) rack mount power supply which converts 230 v , 50/60 hz. Ac power into regulated 14.2 v dc , +/- 1% (at module output*) delivering up to a maximum of 100 a continuous ( up to 115 a surge ) with 5 base level pcb modules. There is provision to connect th...

    A warning circuit monitors the operational condition of the fans. In case of a fan failure, a buzzer will sound and the red led indicating “fan failure” will light up. The unit should be switched off immediately and the defective fan should be replaced. Never load the unit when there is an audible a...

    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. Availability of ac input power 4. Output volt...

    Fan failure warning indicator and alarm : if forced air cooling is stopped due to failure of any one or both the fans, the red “fan failure“ led will be illuminated and an alarm buzzer will be activated. At the same time, a “high” signal will be fed to the opto-coupler for signaling “fan failure” fo...

    7. Regulated output voltage of 14.2vdc +/ - 1% from the modules ( measured at screw terminals s5 and s6 (fig.1) is fed to the positive and negative dc bus bars and from there to the output terminals load+ and load- through the isolating schottky di- ode d1. Although the output voltage at the module ...

    8. If the input a.C. Power is interrupted, the external battery feeds the load instantane- ously through the schottky diode d2 (d2 will by-pass the resistors r1 & r2). Voltage available to the load will be approximately 0.4v lower than the battery voltage due to forward voltage drop across d2. Avail...

    9. The output voltage of the paralleled modules or the common dc bus (before the schottky di- odes d1) can be adjusted between 13.8 v and 14.6 v by adjusting the voltage of each module individually as per the following procedure ( this procedure is explained for sec-100brm which has 5 modules ). The...

    10. Upgrading to higher capacity – installing additional module(s) additional optional module(s) (model no. Sec-2012mpsb-220) can be added to upgrade the out- put current capacity of sec-40brm / sec-60brm / sec-80brm-220 by steps of 20a to a maxi- mum of 100a. For example, an sec-40brm-220 (40 a, wi...

    Removing a defective module 1. Remove the top cover plate by unscrewing the 10 screws. 2. Locate the defective module. Remove the 6 screws from s1 to s6. 3. Remove the input power supply wires from terminals “l” and “n”. Insulate the wire terminals with insulating tape 4. Remove connectors from term...

    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.

    5. The conducted rf noise from these power supplies is limited to the maximum allowable levels by internal filtration. The filtered rf noise currents are by- passed to the chassis of the power supply. The chassis is, in turn connected to the earth ground pin of the ac input power cord (for class 1 u...
