| Product Overview Description & Features SEC-1235 & SEC-1235M are Switched Mode Power Supplies (SMPS) which convert 120V, 50/60 Hz (or 230V, 50/60 Hz*) AC power to regulated 13.8V DC power based on Pulse Width Modulation (PWM) control. Note*: The units are factory preset to operate from an input voltage of 120 VAC, 50/60 Hz.

SECTION 3 | Product Overview 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.

13.8V 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.

Section 5 | Limiting Electromagnetic Interference CAUTION! Conducted and radiated noises in this unit are limited as per the applicable National / Inter- national Standards. In North America, the applicable standard is FCC Part 15(B) for Class “B” Digital Devices for Residential Installations. The corresponding European standard is EN55022, Class “B”...

Section 5 | Limiting Electromagnetic Interference Then, if necessary, relocate either the antenna or the power supply farther apart. 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.

Section 5 | Limiting Electromagnetic Interference proportional to the person’s skin resistance will flow through the person’s body to Earth Ground. The leakage current through the body is higher when the skin contact resist- ance is lower i.e. if the skin is wet or wounded. This leakage current does not return to the power source but is dissipated in Earth Ground.
