GENERAL NOTES
All parameters at 25°C unless otherwise specified.
Off-State dv/dt test method per EIA/NARM standard RS-443, paragraph 13.11.1
Turn-on time for DC control random turn-on versions is 0.02msec.
Input circuitry for DC control version incorporates active current limiter.
PROTECTION
Over Current and Short Circuit
A solid state relay should be protected by a semiconductor fuse.
This type of fuse provides extremely fast opening of the circuit.
A fuse should be selected that has an I t let-through rating that
is less than the I t capability of the SSR, for the same duration.
Transient Over Voltage (P OPTION)
Select "P" option for internal overvoltage protection. At the
presence of high voltage transient the output of the SSR will be
triggered on, and the transient will be passed on to the load circuit
This is a non-degrading method of protection that ensures that
other SSR benefits are maintained.
Earth Bonding (Grounding)
The CKR heatsink is equiped with an earth bonding screw as is
required for Class 1 Protection, in accordance with EN 60950
(VDE 0804).
