GLC40 Commercial

Ac Input

90-264 Vac, 47-63 Hz single phase.

Input Current

Maximum input current at 120 Vac, 60 Hz with full rated output load not to

exceed 1.3 A.

Output Power

Normal continuous output power is 40 W for unrestricted natural convec-

tion cooling, 45 W peak for 60 seconds. During peak load conditions output

regulation may exceed total regulation and noise limits.

Output Regulation

Regulation for multiple-output models measured by ±40% load change from

60% rated load with all other outputs at 60% full rated load and a line volt-

age change from low line to high line. Initial set tolerance is measured with

all outputs at 60% of full rated load. Output voltage V1 requires 1 A load for

proper regulation of multiple output models. Regulation for single-output

models measured by changing from 5% to 50% load or 50% load to full load

in either direction.

Power Limit

Factory set to begin power limiting at approximately 55 W. Fully protected

against short circuit and output overload. Short circuit protection is cycling

type power limit.

Output Noise

0.5% rms, 1% pk-pk, 20 MHz bandwidth, mode. Measured with noise probe

terminals of the power supply.

Transient Response

Main Output: 500 μs typical response time for return to within 0.5% of final

value for a 50% load step change, ∆i/ ∆t<0.2 A/μs. Maximum voltage devia-

tion is 3.5%. Startup/ shutdown overshoot less than 3%.

Overvoltage Protection

Built in on V1 with firing point set per table. OVP firing reduces output #1 and

#2 to less than 50% of nominal voltage in 50 ms.

Voltage Setting

Factory set on standard units with fixed resistors for added reliability. 3.3 V unit

has voltage adjustment pot.

Efficiency

70% typical depending on model.

Turn-on Time

Less than 1 second at 120 Vac, 25°C (inversely proportional 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 limited by internal thermistors. Inrush at 240 Vac, averaged over the first ac

half-cycle under cold start conditions will not exceed 37 A.

Temperature Coefficient

0.03%/°C typical on all outputs.

EMI/EMC Compliance

All models include built-in EMI filtering to meet the following emissions

requirements:
