Spesifikasi AC Current Detection Relay Phase Failure & Sequence Relay


Model : DOC2-2

Description : AC Over Current Relay (0-2A) with 2 Contacts

Utilization:

The DOC2-2 monitors alternating current. Its setting is adjustable from zero to 2.0A. The current circuit

is connected to terminals S1 and S2 either directly or through current transformers.

The DOC2-2 is designed to sense over current. When the measured current is below the setting, two

internal relays will energize and the green Up LED comes ON while the red Trip LED is OFF. If the

current rises above the setting, the relays release and the green Up LED goes OFF while the red Trip LED

comes ON. Contacts 11-14 & 21-24 close in the Up condition and open in the Trip or No Supply

condition.

Model : DOC2-2D

Description : AC Over Current Relay (0-2A) with 2 Contacts and Delay

Utilization:

The DOC2-2D monitors alternating current. Its current setting is adjustable from zero to 2A and the delay

setting is adjustable from 0 to 20 sec. The current circuit is connected to terminals S1 and S2 either

directly or through current transformers.

The DOC2-2D is designed to sense over current. When the measured current is below the setting, two internal relays will

energize and the green Up LED comes ON while the Amber Delay LED and the red Trip LED are OFF. If the current rises

above the setting, the Amber Delay LED comes ON; then after the set delay, the relays release and the green Up LED goes

OFF while the red Trip LED comes ON. Contacts 11-14 & 21-24 close in the Up condition and open in the Trip or No Supply

Model : DUOC-5

Function : AC Under & Over Current Relay (0-5A).

Utilization:

The DUOC-5 monitors under and over alternating current source taken from; e.g a current transformer. It has two

adjustable settings of zero to 5A for under and over current. It is only logical that the under ‘setting’ be lower then

the over ‘setting’. The relay trips if the current of the monitored source drops below or rises above the respective

preset points. There are 2 separate sets of contacts; one for under current (11-14-12) and one for over current

(21-24-22). There are also 2 amber LEDs to indicate normal condition. For under or over trip condition, the

corresponding LED will go off and the corresponding relay will de-energized.
