Output Contacts

Output contacts are rated as follows:

Resistive

120 Vac

Make, break, and carry 7 Aac continuously.

250 Vdc

Make and carry 30 Adc for 0.2 seconds, carry 7 Adc continuously,

break 0.3 Adc.

500 Vdc

Make and carry 15Adc for 0.2 s, carry 7 Adc continuously, break

0.3 Adc

Inductive

120 Vac, 125 Vdc,

250 Vdc

Break 0.3 A, (L/R = 0.04).

Target Indicator

The target indicator may be either internally operated or current

operated (operated by a minimum of 0.2 A through the output trip

circuit). When the target is current operated, the sync output circuit

must be limited to 30 A for 1 second, 7 A for 2 minutes, and 3 A

continuously.

Phase Angle

Selection Accuracy

± 0.5° or ± 5.0% of the front panel setting for degrees, whichever is

greater, for a nominal input frequency of 50/60 hertz, a sensing

input range of 80 to 135 volts, and at 25°C.

Setpoint Accuracy

±0.5° or ±5%, whichever is greater, from a reference measurement

at 25°C, at nominal input frequency and levels, over the specified

operating range of temperature and input voltages.

Timing Accuracy at 25°C

Maximum of 25 milliseconds or 5% of the front panel setting for

time whichever is greater, for a nominal input frequency of 50/60

hertz at 25°C.

TIME Delay Accuracy

(Overall)

±10 milliseconds or ±2%, whichever is greater, of the time delay at

25°C, over the full temperature, voltage, and frequency ranges.

Minimum Voltage

Requirement

Minimum voltage detection circuitry enables the sync-check

circuitry when both line and bus are within operating range of the

relay. Voltage sensing circuits are guaranteed to operate at a

minimum voltage of 60 volts. They are guaranteed not to operate

at voltages less than 20 volts. Some units may operate at voltages

in between these two levels because of the individual

characteristics of specific components. Minimum voltage detection

is usually in the range of 45 to 55 volts.

Voltage Difference Option

Range

Continuously adjustable over the range of 1 to 135 Vac.

Accuracy

Voltage difference setpoint does not vary more than 0.5 V or 5%,

whichever is greater, from a reference measurement at 25°C, with

nominal input frequency, and variation of temperature or voltage

inputs over their specified operating range. This setpoint does not

vary more than 3% from a reading at 25°C over the limited range

of +15 to +40°C.
