Page 4: Description And Features
DESCRIPTION SEC-1235CE is a Switched Mode Power Supply (SMPS) which converts 230 V, 50 Hz AC power to regulated 13.8 V DC power based on Pulse Width Modulation (PWM) control. FEATURES • Based on switched mode technology and PWM control •... -
Page 5: Connections And Operation
CONNECTION AND OPERATION NOTE: The DC output connectors (RED + and Black -) have a tubular hole of diameter 0.2” (5mm) with a set screw. If bare wire with stranded conductors is used to connect the load to the above output connectors of the power supply, the strands will spread out as the set screw is tightened and hence, the set screw will not pinch all the strands. -
Page 6: Battery Charging And Battery Backup
13.8 V when fully charged and the current drawn by the battery reduces a few hundred If a deeply discharged battery is directly charged by SEC-1235CE, the battery will initially draw a very large current and thus, will force the power supply into current limit mode for prolonged period of time. -

TROUBLESHOOTING - GENERAL PROBLEM : Power ON/OFF switch does not illuminate when turned on. PROBABLE CAUSE SUGGESTED REMEDY No power in the AC outlet Check there is power in the outlet. AC side fuse inside the power Replace the fuse inside the unit. supply is blown See fuse ratings at page 11 PROBLEM : AC side fuse blows as soon as power is turned on. -
Page 8: Limiting Electromagnetic Interference
LIMITING ELECTROMAGNETIC INTERFERENCE (EMI) This equipment has been tested and found to comply with the limits as laid down under European Standards EN55022 (Class-B) & EN610000-3 - 2 & 3. These limits are designed to provide reasonable protection against a harmful interference in a residential installation. -
Page 9: Switching Power Supplies & Rf Noise
SWITCHING POWER SUPPLIES AND RF NOISE 1. Switched mode power supplies ( SMPS ) employ high frequency switch- ing and thus, are a source of radio interference, a recipient of radio interfer- ence 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 10 5. The conducted and radiated noises are limited as per the applicable na- tional / international standards. In North America, the applicable standard is as per FCC Part 15(B) for Class “B” digital devices. The European standard is as per EN55022, Class “B” & EN610000-3-2, 3. Thus, the RF interfer- ence is limited but not entirely eliminated.
- Page 11 7. Following additional guidelines may be followed to reduce the effects of RF noise: Use additional appropriate AC radio frequency interference (RFI) power line filter rated for minimum 5 A immediately before the AC input of the power supply. For example, consider suitability of model # 6VN1 from “N”...
