Model Selection Guide

Mechanical Dimensions

Notes:

1. Output voltage tolerance is measured

at nominal input and 60% load.

2. Line regulation is measured at nom-

inal load over a range of 100 to 240

VAC.

3. Load regulation is specified for a load

change of 60% ±40% (of full load).

4. Output ripple is measured at 20 MHz

bandwidth using 0.1 µF and 10 µF

capacitors connected in parallel as

close to the power supply terminals

as possible.

5. The maximum output current is given

for each individual output. The maxi-

mum output power rating for the unit

should not be exceeded. By adding 30

CFM of airflow (see derating curves)

all models may be used at higher

power levels. Contact the factory for

more information.

6. Each unit includes an input fuse

(250V/2A). Since this fuse is not field

replaceable, it is recommended that

an external fuse of the same size be

used on the input of the power supply

for protection.

Safety Ground:

The mounting holes marked “Use metal standoffs” should be

connected to the system earth ground via metal spacers or

a cable. The input side mounting hole marked “FG” provides

the safety earth ground for the unit. This connection should

be locked to prevent possible loosening. Connecting the

output side mounting hole improves EMI.
