About the Load

Unlike other general DC power supplies, the KDS6-0.2TR is optimized as a low-
noise voltage source. For this reason, the KDS6-0.2TR is not suitable for use in
applications intended to drive loads with abruptly changing current.

If the peak current is lower than the maximum permissible current for each channel,
the KDS6-0.2TR may be used without activating the OCP function. However, volt-
age variation on the order of ±0.1 V to ±0.5 V remains likely for several ms

lowing an abrupt current variation.

When a load subject to abrupt current change is to be connected to the KDS6-
0.2TR, it is recommended that you monitor the voltage waveforms on an oscillo-
scope or the like.

Sample uses in which abrupt current changes occur

When the KDS6-0.2TR is used to drive a relay coil or resistance, which
is switched on/off by an external switch:

If the load is switched on/off by a switch, the current will be subject to significant
fluctuations. Use the OUTPUT on/off function with the KDS6-0.2TR to the full
extent practicable.

In cases in which an induction load such as a relay is connected, insert a diode in
parallel with the coil to prevent problems due to back-electromotive force.

When the KDS6-0.2TR is used as a power source for communication
modules or the like that perform TDMA communication:

Some module types give rise to significant current fluctuations when switching
between transmission and reception.

This problem can sometimes be resolved by connecting a low-ESR capacitor (100

F

to 1000
