Mechanical Notes:

Notes:

1. Output voltage tolerance includes set-up tolerance,

line regulation and load regulation.

2. Ripple & noise is measured using equipment with 20

Mhz of bandwidth. Connection to the unit under test

is made with a 12 inch length of “twisted pair” wires

terminated with a set of 1.0 μF & 4.7 μF capacitors

connected in parallel.

3. Overload protection is foldback current limiting.

The unit recovers automatically when the fault is

removed.

4. Over voltage protection is a shut down type. The

power to the unit must be manually reset to re-

cover.

5. Over temperature protection shuts down the output.

The unit recovers automatically when the tempera-

ture goes down. The thermal detector is mounted on

the heat sink of the power semiconductor.

6. Isolation resistance is given for Input/Output; Input/FG

and Output/FG.

7. To mount the unit to the DIN rail, tilt the unit rear-

wards from the top, fitting the mount over the top

of the rail. Press back on the bottom front of the unit

until it locks in place on the rail. To remove the unit

from the rail, pull the removal clip at the bottom rear

of the unit downward with a screw driver. With the

clip down, lift up on the unit from the bottom front

until it clears the rail. Before installation or removal all

wiring should be disconnected and the main power

to the system shut off.

8. When wiring the supply, all lines should be as thick

and short as possible. AWG 14 wire is recommended

for the DR-45 series.

9. The units should be mounted so they are vertically

orientated. Air flow (if it is provided) would optimally

flow from the bottom to the top of the unit.

10. It is recommended that a fuse be used on the input

of a power supply for protection. See the table

above for the correct rating.
