Notes:
1. Output voltage tolerance includes set-up tolerance, line regula- Derating Curve - Output Power vs Ambient Temperature
tion 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 recov-
ers automatically 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. For
TSW1, the thermal detector is mounted on the heat sink of
the power semiconductor. For TSW2, the thermal detector is
mounted on the heat sink of the power Diode.
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.
Static Characteristics
8. When wiring the supply, all lines should be as thick and short as
possible. AWG 14 wire is recommended for the DRT-960 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.
