Notes:
1. Output voltage tolerance includes set-up tolerance, line regulation and
load regulation. For the 12V output model, tolerance is ±2.0%.
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 auto-
matically when the fault is removed.
4. Over voltage protection is a clamp type. The power to the unit must be
manually reset to recover.
5. Over temperature protection shuts down the output. The unit recovers
automatically when the temperature 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 rearwards 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-120
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.
