Description
The new range of Hobut DIN rail mounting power meters feature seven selectable colour backlight LCD screens. The range is easy to use and features user-programmable CT & VT ratios that can be used on any single or 3 phase system.
The products feature a unique set point relay trip output that can be assigned to eight different measurements.
Application
The range is a cost effective replacement for traditional panel meters and is suitable for low, medium and high voltage control panels, gensets, building management systems, power management and more.

ORDERING INFORMATION
SET POINT RELAY
The relay output can be programmed to be used as a pulsed output or instead as a set point relay.
When used as a set point relay:-
• up to 8 parameters can be assigned to the relay
• whichever parameter reaches the set point will cause the relay to trip
Relay Mode: can be set to over, under or window mode
Trip: can be set from 1% to 250% of input
Reset (differential): can be adjusted from 1% to 250% of input
Group Logic: can be set to 1, 2 or 3 phases or the sum or the average
Time Delay: can be programmed from 1 to 1800 seconds
Colour: LCD backlight can be set to change colour when relay as tripped
Relay State: can be programmed to energise on trip or de-energise on trip
