Functions
Pulse/Ramp Sequence (Option)
Following output controls of A to E are applicable.
A. Pulse Sequence
ta, tb, tc and toff can be set in 0.0 to 9999h59m59.9s, respectively
Sequential operation is possible by using voltage and current set on each memory a, b, and c in combination with a multi-set function. Not only continuous operation, but also it is possible to specify the times. It is best fit to evaluation tests for products as various operations, like as repeat of a and b only or repeat of b, c and off only, are enabled by setting time of memory a, b, c or off to 0.0.
B. Ramp
t1 and t2 can be set to 0.0 to 9999 h 59 m 59.9 s, respectively
It enables to make ramp action up to set voltage or current (or from the set voltage or current to 0V or 0A). It is useful to like to rise (reduce) voltage or current slowly.
* For ramp action, it is possible to select [both of set voltage and current], [only set voltage] or [only set current].
C. Pulse Sequence + Ramp
t1 to t4, ta to tc and toff can be set in 0.0 to 9999 h 59 m 59.9 s, respectively
It is also possible to use pulse sequence combined with ramp action. If the multi-set function is combined with the too, it is able to make sequence action by using voltage or current set on memory a, b and c. Not only continuous operation, but also it is possible to specify the times.
It is useful in various aspects as it is possible to rise (reduce) voltage or current slowly up to 20 set value.
D. Delayed Trigger Ramp
* t1 and t2 can be set in 0.0 to 99.9s, respectively.
* ton can be set in 0.1s to
9999h59m59.9s and toff can be set in 0.0 to 9999h59m59.9s
This is one of the combinations with Delayed Trigger Function and Ramp Function, after OUTPUT is made ON, ramp output is started in time delay.
E. Master Follow

Pulse sequence actions at master-slave and output signal to slave units at ramp action are transmitted. By this function, it is possible to make slave units to output on different output conditions from the master unit.
* Only for -LGmb models
External Analog Remote Control
- External Output ON/OFF
- Output can be turned ON/OFF by relay or TTL signal.
Logic of OUTPUT can be made reverse.
- Output Control (Voltage, Current)
- Use control voltage as floating but not grounding.
Potential on COMMON is the same one of +output terminal. If COMMON in customer's equipment is grounded, not only power supply can not be controlled, but also damage of equipment may be caused. And if multi-channel and non-isolated Programmable Logic Controller (PLC) is utilized, please take care that ground of other equipment is connected through the PLC in a certain case.
- Output Monitor (Voltage, Current)
- Output of Status
- COMMON is floating with the output of open collector for each COMMON.
Voltage resistance 30 Vdc, Sink current ≤ 5 mA
- Remote Sensing
- Prevent to degrade stability due to voltage drop (Vo-VL) by resistance (R) in output wiring or contact resistance. (up to max. 0.5 V)
Parallel Operation by One Control
One master unit can control several slave units that are parallel connected. It is possible to increase output current by connecting two units of the same model power supply in parallel.
