†
Type R power supply initially requires 14 Vdc to begin operating. Once operating, the voltage
may be reduced to 12 Vdc and operation will continue.
Output Circuits
Output contacts are rated as follows:
Resistive:
120/240 Vac
Make 30 A for 0.2 seconds, carry 7 A continuously, and break 7 A.
250 Vdc
Make 30 A for 0.2 seconds, carry 7 A continuously, and break 0.3 A.
Inductive:
120/240 Vac,
Make 30 A for 0.2 seconds, carry 7 A continuously, and break
125/250 Vdc
0.3 A. (L/R = 0.04).
