Page 4: Description And Features
DESCRIPTION SEC-1235 / SEC-1235M are Switched Mode Power Supplies (SMPS) which convert 120 VAC, 60 Hz (or 230 V, 50 / 60 Hz *) AC power to regulated 13.8 V DC power based on Pulse Width Modulation (PWM) control. *Note: The units are factory preset to operate from an input voltage of 120 VAC, 60 Hz. -
Page 5: Connections And Operation
CONNECTION AND OPERATION WARNING ! The unit has been pre-set to operate from an input voltage of 120 VAC. Hence, before plugging the unit to the AC outlet, please ensure that the local AC power supply voltage is 120 VAC. Operation from 230 VAC is possible by changing internal settings. -
Page 6: Battery Charging And Battery Backup
13.8 V when fully charged and the current drawn by the battery reduces a few hundred mA. If a deeply discharged battery is directly charged by SEC-1235 / SEC-1235M, 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 for a class B digital device, pursuant to Part 15(B) of the FCC Rules. 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 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 10 The receiver may “hear” the power supply. A slowly moving, slightly buzzing carrier heard in the receiver may be caused by the antenna being too close. As with the transmitter related noise pick up, a loose coaxial connector or a broken or a missing ground may aggravate this problem. Normally these noises will be below the background or “band”...
- Page 11 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 10 A immediately before the AC input of the power supply. For example, consider suitability of model # 10VN1 from “N”...
