Undervoltage Sensing Input Range

High Range:

0.5 to 12 Vac (sensing input range 1, 2, 5, or 6) or 1.0 to 24 Vac

(sensing input range 3, 4, 7, or 8).

Low Range:

0.1 to 2.5 Vac (sensing input range 1, 2, 5, or 6) or 0.2 to 5.0 Vac

(sensing input range 3, 4, 7, or 8).

Pickup Accuracy

1 to 24 Vac range:

±

2% or 20 millivolts

All other ranges:

±

2% or 10 millivolts

Overvoltage Sensing Input Range
Ranges selectable by unit type for 50 or 60 Hz operation: 1 to 20 Vac, 10 to 50 Vac, 2 to 40 Vac, 20 to

100 Vac.
Pickup Accuracy

120 Vac (sensing input range 1, 2, 5, or 6): ±2% or 100 millivolts, whichever is greater

240 Vac (sensing input range 3, 4, 7, or 8): ±2% or 200 millivolts, whichever is greater

Dropout
98% of pickup within 7 cycles.

Timing Characteristics
Instantaneous:

Less than 70 milliseconds (60-Hz relays) or less than 84 milliseconds

(50-Hz relays) for a voltage level that exceeds the pickup setting by

5% or 1 volt, whichever is greater

Definite:

Adjustable from 00.1 to 99.9 seconds, in steps of 0.1 seconds.

Accuracy is within 2% or 100 milliseconds, whichever is greater. (A

setting of 00.0 provides instantaneous timing.)

Inverse:

Response time decreases as the difference between the monitored

voltage and the setpoint increases. The inverse time characteristics

switch is adjustable from 01 to 99 in 01 increments. Each position

corresponds to a specific curve except 00, which is instantaneous.

Accuracy is within ±5% or 25 milliseconds (whichever is greater) of

the indicated time for any combination of the time dial and within

±

2% of the voltage magnitude or 100 millivolts (for the 120 Vac

sensing range) or 200 millivolts (for the 240 Vac sensing range)

(whichever is greater) from the actual pickup value. Inverse time is

repeatable within ±2% or 25 milliseconds (whichever is greater) for

any time dial or pickup setting. The characteristic curves are defined

in Figures 1-3 and 1-4.
