Mechanical Dimensions
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.
