AUXILIARY SUPPLY
A high efficiency switchmode power supply is incorporated which
provides a low burden to the auxiliary supply.
Low range model:
20-70V DC
High range model:
40-300V DC & 40-275V AC
AUXILIARY SUPPLY BURDEN
(At 110V DC)
Quiescent:
Less than 4W
Maximum:
Less than 10W
OPERATING TIME OF ARC FAULT DETECTION
Arc fault trip contacts guaranteed to pick up in less than 10ms
including bounce. Typical operate time is 7ms.
Reset time of the arc fault element is 2s.
CRO trace showing nominal operation time of the trip contacts at
7ms. First contact touch at 6.25ms and fully closed by 7.25ms.
Operation in <10ms is considered acceptable as current check
relay operate time is ~15ms.

STATUS INPUT OPERATING VOLTAGE
An internal configuration switch is provided to select status input
operation for DC only or AC/DC. This setting may be pre defined
when ordering.
18 - 300V DC
Set Configuration Switch to
ON
In this mode the universal status input will reject AC signals that
may be induced on the control wiring. Suitable for high security
applications where a DC battery supply is available.
18 - 300V DC & 18 – 275V AC Set Configuration Switch to
OFF
In this mode the universal status input is designed to operate on
both AC & DC input voltages. Suitable for applications where an
AC auxiliary voltage is available such as transformer or generator
control panels.
STATUS INPUT MINIMUM OPERATING CURRENT
10mA P/U for 1ms then reducing to1.5mA after 4ms.
RESET
Press the front reset button or pulse the reset status input.
