KEPCO SINGLE OUTPUT 15 WATT
HIGH FREQUENCY SWITCHING POWER SUPPLIES
I — INTRODUCTION
The Kepco FAW 15 Watt Series low profile high frequency switching power supplies employ flyback conversion and operate with a 70% efficiency with
either a-c or d-c input. A thermistor soft-start circuit limits start-up surge. Surface mount technology permits efficient component layout for minimum
mounting space. Four models may be selected for outputs of 5, 12, 15 or 24V. “POWER OK” logic and a green “POWER OK” light are provided. A steel
cover (Model CA 24) is available as an option. Output voltage may be adjusted with a trimmer accessible near the input-output terminal strip. When the
input is cut off, the output is maintained for 15 milliseconds minimum. EMI filtering meets FCC Class B rating and VDE 0871 Class B rating. This page
contains specifications for each model of the FAW 15 Watt Series. Environmental specifications for each model are the same.
II — SPECIFICATIONS
The following specifications apply to FAW 15 Watt Series models. Other models are also available; consult your Kepco representative for their specifi-
cations.
INPUT:
Voltage: 120V a-c/240V a-c nominal; Range 85-264V a-c; 110-370V d-c.
Frequency: Nominal 50-60 Hz; Range 47-440Hz (at 440Hz leakage current exceeds UL/VDE safety spec.limit).
Current (nominal output at rated load): @120V a-c rms: 0.3A typ., 0.4A max; @240V a-c rms: 0.2A typ., 0.3A max.
Initial Turn-on Surge: (one-half of first input cycle): @120V a-c rms, 22A max., @240V a-c rms, 34A max.
STABILIZATION:
Source Effect: Range 85-132V a-c or 170-264V a-c, 1.0% typ.; 2.0% max.
Load Effect: Range 10%-100% load, 1.0% typ.; 2.0% max.
Temperature Effect: Range 0oto 50oC, 1.0% typ.; 2.0% max.
Combined Effect: 2.6% typ.; 4.0% max. (includes source, load, and temperature effects).
Drift: 0.1% typ.; 0.5% max. (1/2 hr-8 hr at 25oC).
RECOVERY CHARACTERISTICS: A step load change from 50% to 100% produces less than +4% output excursion. Recovery occurs to within
+1% of the original setting in <2 ms (tr or tfequal to or greater than 50µsec at load change).
START-UP TIME: 500 ms. maximum.
HOLD-UP TIME: 15 ms. min (100V a-c), 20 ms. typ. (120V a-c).
DIELECTRIC STRENGTH:
Between input and output: 2KV a-c for one minute.
Between input and output with Y-capacitor removed: 3.75KV a-c for one minute.
Between input and case (ground): 2KV a-c for one minute.
INSULATION RESISTANCE: Between input and ground, output and ground, input and output;
100 Megohms min. (500V d-c).
