Recommended Relay Drive Conditions

Drive under conditions. If it is impossible, please inquire to NEC/TOKIN

Nonlatch type

Performance Data

Coil Temperature Rise
Temperature is measured by coil resistance.

Switching Capacity
This is allowed maximum value. Inquiry for NEC/TOKIN under maximum value at continuous use.

Maximum Coil Voltage
This is a maximum value of permissible alteration. Inquiry for NEC/TOKIN at continuous use.

Applied Voltage Vs. Timing (Sample : UA2-5NE)

Operate and Release Voltage Vs. Ambient Temperature
This shows a typical change of operate (release) voltage. Maximum value of operate is estimated, so it must be applied more than this value for safety operation. In case of “hot start operation”, please inquiry for NEC/TOKIN.

Running Test (Nonload)
