Functions
Pulse/Ramp (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 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 operation
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 the set voltage or current (or from the set voltage or current to 0 V or 0 A). It is useful to like to rise (reduce) voltage or current slowly.
* As for the lamp operation, you can select “Both setting voltage and current”, “Voltage setting only”, or “Current setting only”.
C. Pulse & Ramp
t1 to t4, ta to tc and toff can be set in 0.0 to 9999 h 59 m 59.9 s, respectively
Pulse and ramp controls can also be combined. In addition, it can be combined with the multi-set function. Therefore, Sequence operation is possible using the voltage and current values set in the "a", "b", and "c" memories. Repeated and continuous operation, as well as the number of times, can be set. The power supply itself alone can be used to slowly and repeatedly increase or decrease voltage and current values up to twenty set values, making it useful in a variety of applications.
D. Delayed trigger ramp
* t1 and t2 can be set respectively in 0.0 to 99.9 s.
* ton can be set in 0.1 s to 9999 h 59 m 59.9 s and toff can be set in 0.0 to 9999 h 59 m 59.9 s
This is one of the combinations with delayed trigger function and ramp function, after OUTPUT is made ON, ramp output is started in time delayed.
E. Master Follow
Master-follow is a function that allows a slave equipment to follow the output status of the master equipment in a master/slave connection. The output status of the master equipment is transmitted to the slave equipment to enable interlocked operation. The master and slave can be set to different modes of operation, allowing for complex testing.
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 as one of the positive output terminal. If COMMON in the customer's equipment is grounded, not only power supply can not be controlled, but also damage to equipment may be caused. And if a multi-channel and non-isolated Programmable Logic Controller (PLC) is utilized, please take care that the 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 the open collector for each COMMON.
Voltage resistance 30 Vdc, Sink current ≤ 5 mA
- Remote Sensing
- Prevent 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.
