Response time 500 ms

Nominal excitation current : 3A

Maximum excitation current 7A for 10 sec.

Features:

Storage: -55°C ; +85°C

Operation : -40°C ; +65°C

Voltage regulation: ± 0.5%.

Voltage supply/sensing range 85 to 139 V (50/60 Hz)

Rapid response time (500 ms) for a transient voltage variation amplitude of ±  20%

Voltage setting P1

Stability setting P2

Power supply protected by 8 A fuse, slowblow action (tolerates 10 A for 10 s)

The fuse is impregnated in the resin, therefore it can not be replaced.
