This latest addition to our Power Supply Line has been

introduced after much demand. Endless applications will be

more cost effective with DC power attainable directly from

your high line. All power supplies listed here have an input

voltage of 240/480 VAC

Agency Approvals:



Designed to meet UL 60950-1/ CSA 60950/ and

EMC Directives

Value Added Options Include:

Operating Temperature: 0°C to 50°C full rated load, derate

linearly to 40% at 70°C.



Screw terminal block

Overvoltage protection (standard on 5 volt models)

Mounting spacers

Storage Temperature: -55°C to +85°C.

Vibration: Per MIL-STD-810B, method 514, procedure 1,

curve AB (to 50Hz).

Input fuse

Shock: Per MIL-STD-810B, method 516, procedure V.

Safety Standards: Designed to meet safety regulations of UL,

CSA, VDE, CE and other international standards.

Finish: Clear aluminum chassis. Chassis also serve as heat sink.

Mounting: Units can be mounted on several surfaces.

Mounting holes will accept “press fit” # 6-32 threaded fasteners.

For efficient cool, allow unrestricted airflow.

Specifications:

AC Input: 240/480 VAC +/-10%, 47-63Hz. See

chassis ID label for jumper and line fusing requirements.

DC Output: See Selection Guide for voltage/current ratings. The output is

floating; either positive or negative terminal can be grounded. Output

adjustment range is +/‒10%, except variable 10-18V outputs.

Line Regulation: +/-0.05% for 10% line change.

Load Regulation: +/-0.05% for 50% load change.

Thermal Regulation: +/-0.02% per °C maximum, +/-0.005% per °C typical

Output Ripple: 2mV rms maximum, 3mV P-P.

Forced air cooling may be recommended.

Dynamic Response: 30 microseconds for 50% load change.

Stability: +/-0.3% for 24 hour period after 1 hour warm-up.

Short Circuit and Overload Protection: Foldback current limiting,

set at 120% of nominal

Overvoltage Protection: Crowbar overvoltage protection is standard on all

5 VDC main outputs and is factory set at 6.2V +/-0.4V (fixed). Optional

universal OVP module adjustable from 4.5 to 36V is available

for other models.

Remote Sensing: Standard on all outputs above 30 watts.

Remote sense will compensate for a cable drop of 0.25V.

Protected against open or shorted sense leads. Twisted pair sense

leads are recommended.

Efficiency: 5V units: 45%; 12 and 15V units: 55% 24V and higher units:

60%.
