Type R power supply initially requires 14 Vdc to begin operating. Once operating, the input

voltage may be reduced to 12 Vdc and operation will continue.

Target Indicators

Electronically latched, manually reset target indicators are optionally available to indicate closure of the

trip output contacts. Either internally operated or current operated targets may be specified. Internally

operated targets should be selected when normally-closed (NC) output contacts are specified.
Current Operated Targets

Minimum Rating ......................... 200 mA flowing through the trip circuit

Continuous Rating ...................... 3 A

1 Second Rating ......................... 30 A

2 Minute Rating .......................... 7 A

Negative Sequence Voltage

Pickup

Setting Range ............................ 2 to 32% of nominal

Increment ................................... 2%

Accuracy .................................... ±1 unit of the percent setting of the negative sequence voltage at

nominal frequency (50 or 60 Hz as defined by the style number)

Dropout ............................................. 98% of pickup
