4.4.7 Foldback Protection
1. Foldback protection will shut down the power supply output if the load current exceeds the current
2. To arm the Foldback protection, the FOLD pushbutton should be pressed so the FOLD LED
3. Activation of the Foldback protection disables the power supply’s output, turns on the ALM (alarm)
4. There are 2 modes of releasing an activated Foldback protection.
4.4.8 Output ON/OFF Control
The ON/OFF circuit has two controls; a front panel pushbutton and a rear panel connection. priority is
given to the rear panel connection.
2. Front panel ON/OFF Control
1. Rear panel ON/OFF Control
Contacts 9, 10 at the rear panel External Control connector (fig. 4-2, item 4) serve as ON/OFF
terminals. Either short circuit or TTL ‘0’ level enables the power supply output and open circuit or TTL ‘1’
level disables the power supply’s output. An open collector transistor can be used for the ON/OFF
control as shown in fig. 4-3, with sink current ability of more than 2.5mA. Please note that pin 10 (COM)
is internally connected to the - Sense potential, therefore for floating ON/OFF Control a photocoupler
should be used as shown in Fig. 4-4.
Fig. 4-3: ON/OFF Control, references to - Sense.
The Front Panel ON/OFF is controlled by the OUT pushbutton. To enable the output, OUT pushbutton
should be pressed so that OUT LED illuminates. The operation of OUT pushbutton is enabled only if the
rear panel ON/OFF is configured to ‘ON’.

greater than the current limit level, the output will be disabled again and Foldback indicators will

Current mode depending on the load characteristics and power supply setting.
