M850 MULTIFUNCTION

METERS

DESCRIPTION

The new range of Hobut multifunction panel meters

feature 96 x 96mm sizes complete with unique blue

LED screen, which can be seen in direct sunlight. The

range is easy to use, features user-programmable CT &

VT ratios, and can be used on any single or 3 phase

system with any input voltage without re-programming.

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.

STANDARD FUNCTIONS:

Phase Voltage (V)

Phase to Neutral Voltage (V)

Phase Current (I)

Frequency (Hz)

Active Power (W)

Active Energy (kWh)

Reactive Power (VAr)

Apparent Power (VA)

Reactive Energy (VArh)

All models feature the

following user-programmable

functions:

• Current Transformer Ratio

• Voltage Transformer Ratio

• Baud Rate, Parity, Stops

Both pulsed output

(for Wh or VArh) and

RS 485 output

(Modbus protocol)

are plug in options

which can be

supplied with the

multifunction meter.

If purchased

separately please use

ordering codes on

right.
