3-4 Protection
This section describes the outline of the protective function.
For the settings of the protection, please refer to [4-2 Operation for Protective Function].
3-4-1 Overvoltage Protection (OVP)
There are two protective functions: voltage limit and output cutoff.
Select either one.
The voltage limit protection can be set to both positive and negative polarities separately.
The output cutoff protection cuts off the output by comparing a value measured in effective value with
the cutoff setting value.
Although the response time of the output cutoff protection is several hundred milliseconds, another
high-speed voltage limit protection works at 110% of the rating to protect the unit and load.
[Voltage limit protection]
Setting range: 0.1 to +rated value x 110% for positive and -0.1 to -rated value x 110% for negative
Setting unit: 0.1V
[Output cutoff protection]
Setting range: 0.1 to rated value x 110%
3-4-2 Overcurrent Protection (OCP)
Like the overvoltage protection, there are two protective functions in the overcurrent protection:
current limit and output cutoff.
Select either one.
[Current limit protection]
Setting range: 0.1 to +rated value x 110% for positive and -0.1 to -rated value x 110% for negative
Setting unit: 0.1V
[Output cutoff protection]
Setting range: 0.1 to rated value x 110%
The current limit protection has two types: one limits high-speed pulse current and another
steady-state current.
The above current limit protection is for the steady-state current and its response rate is approx. one
millisecond as same as the voltage limit protection.
