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 ANY OF THE FANS FAILS, LIGHT AND SOUND ALARMS WILL BE ACTIVATED. - Page 5 # 2 AWG | UP TO SEC-80BRM-220 80 A # 4 AWG | 6’ SEC-60BRM/SEC-40BRM-220 UP TO 60 A # 6 AWG | DISTANCE ENSURE THAT THE AC POWER IS SWITCHED OFF WHEN ANY DEVICE IS BE- ING CONNECTED TO THE POWER SUPPLY.

Page 6: Description And Application
SEC-60BRM-220 has 3 PSMs of 20 A each providing a total of 60 A • SEC-40BRM-220 has 2 PSMs of 20 A each providing a total of 40 A COOLING AND WARNING FOR FAN FAILURE The heat generated due to internal power dissipation is removed by forced cooling through two high power D.C. -
Page 7: Front Panel Controls And Indicators
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 ALARM AND THE FAN FAILURE LED IS ILLUMINATED. -

140A for SEC-100BRM-220 or 112A for SEC-80BRM-220 or 84A for SEC-60BRM-220 or 56A for SEC-40BRM-220 (the output voltage will be approximately 2.7V), the unit will shut down (will enter hiccup mode). The PSM status LEDs will start flashing and PSM status signal for re- mote indication will oscillate between High and Low. -
Page 9: Installation And Operation
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”... -
Page 10: Operation Of Battery Back-Up
OPERATION OF BATTERY BACK-UP WARNING! THE BATTERY SHOULD BE LOCATED IN A WELL VEN- TILATED AREA TO SAFELY DISSIPATE HYDROGEN GAS PRODUCED DURING THE CHARGING PROCESS. D1, D2 SCHOTTKY DIODE: 30V, 180A R1, R2 POWER RESISTOR: 0.78 OHM, 35W STATIC LOAD RESISTOR: 120 OHM, 5W FUGURE A. -
Page 11: Output Voltage Adjustment
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. -
Page 12: Installation And Removal Of Modules
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 ). -
Page 13: Output Voltage Adjustment
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, with 2 modules) can be upgraded to SEC- 60BRM-220 (60A) by adding 1 more module or to SEC-80BRM-220 (80A) by adding 2 more mod- ules or to SEC-100BRM-220 (100 A) by adding 3 more modules. -
Page 14: Trouble Shooting
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. Remove the input power supply wires from terminals “L” and “N”. Insulate the wire terminals with insulating tape 4. - Page 15 “ PSM STATUS ” LED(S) DOES NOT LIGHT UP The associated module has become defective. The unit will still operate · normally as the remaining working modules will share a higher load. The unit will go into current limit and the output voltage will drop if the load drawn is more than the combined maximum rated output of the remaining modules.

Page 16: Limiting Electromagnetic Interference
LIMITING ELECTROMAGNETIC INTERFERENCE (EMI) 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 ). - Page 17 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 units).
- Page 18 Twist the positive and negative wires from the output of the power supply to the radio The DC side positive and negative outputs of these power supplies are iso- lated from the chassis. As explained at paragraph 5 above, the noise currents are filtered to the chassis ground and the chassis ground is connected to the earth ground through the earth ground pin of the AC power outlet receptacle.
