Specifications
AC Input
90-264 VAC, 47-63 Hz single phase.
Input Current
Maximum input current at 120 VAC, 60 Hz with full load: 0.5 A.
Hold-Up Time
10 ms minimum from loss of AC input at 20 W load, nominal line (120 VAC).
Output Power
Normal continuous output power is 20 W, 25 W peak for 60 s.
Overload Protection
Fully protected against short circuit and output overload. Short circuit
protection is cycling type power limit. Factory set to begin power limiting
at approximately 27 W.
Unless otherwise noted, all parameters are nominal values measured at 120 VAC @25˚C and 0-95%
relative humidity, non-condensing. For limits at unusual operatiing conditions, consult factory.
Output Noise
0.5% RMS, 1% Pk-Pk, 20 MHz bandwidth, differential mode. Measured with
scope probe directly across output terminals of the power supply with load
terminated with 0.1μF capacitor.
Transient Response
Main Output - 500 μs typical response time for return to within 0.5% of final
value for a 50% load step within the regulation limits of minimum and
maximum load,
∆i/∆t<
0.2 A/μs. Maximum voltage deviation is 3.5%.
Start-up overshoot less than 5% under nominal conditions; less than 2%
under all conditions at shutdown.
Switching Frequency
70 kHz +/-10 kHz.
Voltage Adjustment
See table for individual model features. Adjustable voltage outputs
are preset at factory. Outputs are capable of a minimum of +/- 5% change
from nominal setting.
EMI/EMC Compliance
All models include built-in EMI filtering to meet the following emissions
requirements:

COMPLIANCE LEVEL
EN55022 Class B; FCC Class B
EN61000-4-2, Level 3
EN61000-4-3, Level 3
EN61000-4-4, Level 3
EN61000-4-5, Level 3
Overvoltage Protection
Built in with firing point set per grid at top of next page. OVP firing shuts
down the converter.
Efficiency
72 to 80% depending upon model.
Turn-on Time
Less than 1 s at 120 VAC, 25°C (inversely proportionate to input voltage and
thermistor temperature).
Input Protection
Internal AC fuse provided on all units. Designed to blow only if a catastrophic
failure occurs in the unit. Fuse does not blow on overload or short circuit.
Inrush Current
Inrush is limited by internal thermistor. The inrush at 240 VAC, averaged
over the first AC half-cycle under cold start conditions will not exceed 37A.
Temperature Coefficient
0.03%/°C typical on all outputs.
Safety Approvals
SL Power Electronics, Corp. declares under our sole responsibility
that all GECA models are in conformity with the applicable requirements of
EN60950 following the provisions of the Low Voltage Directive 73/23/EEC.
All GECA models are approved to UL60950-1: 2003,
CSA-22.2 No. 60950-1-03, IEC and EN60950-1
Temperature Range
Designed for 0 to 45°C operation at full rated output power; derate output
current and total output power by 2.5% per °C above 45°C.
MTBF
120kHrs.
