Functions
Remote Control Connector (Control)
D-Sub 15-pin female (mating connector enclosed).
Remote/Local change

Output | External relay | Open collector |
---|---|---|
Remote | Short | VCE ≤ 0.4 V |
Local | Open | VCE ≥ 2 V |
Sink Current ≥ 10 mA
External output ON/OFF

Output | External relay | Open collector |
---|---|---|
ON | Short | VCE ≤ 0.4 V |
OFF | Open | VCE ≥ 2 V |
Sink Current ≥ 10 mA
- When Output state auto-recovery prevention (former: power failure protection) is ON: Outputting of high voltage is possible only when both of OUTPUT switch and external output ON/OFF are ON.
- When Output state auto-recovery prevention (former: power failure protection) is OFF: Outputting of high voltage is possible when external output ON/OFF is ON. (under remote control)
Output Control Remote analog programming

Output voltage | Vcon |
---|---|
0 to Maximum | 0 to 10 V Input impedance ≥ 1 MΩ |
It is necessary to maintain "Icon > Vcon" when EPR is controlled with CV mode.

Output current | Icon |
---|---|
0 to Maximum | 0 to 10 V Input impedance ≥ 1 MΩ |
It is necessary to maintain "Vcon > Icon" when EPR is controlled with CC mode.
Output Monitor

Monitor output is 0 to +10 V for 0 to Max. Output impedance 1 kΩ
Interlock

It is possible to output in external relay short or a status of VCE less than 0.4 V. Output will be cut off when open or 2 V or more. To resume the output again, turn POWER switch ON after resetting by turning POWER switch OFF in a status of short or less than 0.4 V
Sink current ≥ 10 mA

Pulse/Ramp Sequence
Following output controls of A to C are applicable.A. Pulse Sequence
Sequential operation is possible by using voltage and current set on each memory a, b, and c in combination with multi-set functions. Not only continuous operation, but also it is possible to specify the times.
It is the best fit evaluation test 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.
ta, tb, tc, and toff can be set respectively in 0.0 s to 9999 h 59 m 59.9 s.
B. Ramp
It enables to make ramp action up to 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".
t1 and t2 can be set respectively in 0.0 to 9999 h 59 m 59.9 s.
C. Combination of Pulse and Ramp Sequence
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.
t1 to t4, ta to tc and toff can be set respectively in 0.0 s to 9999 h 59 m 59.9 s.
