Control of up to two low voltage disconnects (magnetically latched contactors) per I/O board*

•

Network connectivity (web access)

•

System voltage metering for primary system DC supply. (e.g., 48V primary DC output)

•

Load, battery and rectifier current metering and alarms

•

Active rectifier and converter current share

•

Automatic system voltage control

•

Effectively unlimited alarm thresholds as standard, for use with multiple DC outputs

•

Advanced monitoring, display and logging of battery packs, and system performance data

•

Advanced hybrid site control and monitoring with patented anti-stall feature for generators.

•

Phase balance controls for multi-phase and single-phase AC input management

•

Sophisticated programmable logic control

•

For lead-acid external batteries -

•

◦ Battery and room temperature metering and alarms (when fitted with optional temperature

sensors)

◦ Optional complete or battery mid-point monitoring (when fitted with optional battery monitor

cards)

◦ Temperature compensation of float voltage (when fitted with optional temperature sensors)

◦ Manual equalize charging to prolong the life of the batteries

◦ Periodic equalize charging to prolong the life of the batteries

◦ Fast charging after battery discharge

◦ Battery capacity remaining indication

◦ Battery testing facility

◦ Battery current limit

Six user defined General Purpose Inputs ("GPIPs") which can be software configured as either digital or

•

analogue inputs* (up to 10 may be made available under special circumstances)

Six relay outputs*

•

I/O Expansion card capability*

•

Expanded serial and CAN communications – up to 5 I/O boards can be connected to a single EM4x *

•

Note: the addition of an I/O Expansion card to the EM4x allows for analogue inputs and increases the

number of digital inputs and relay outputs available. The controller allows for these new

inputs/outputs to be logically combined allowing a degree of control of peripheral functions. E.g., a

temperature triggered room fan or humidity detection.
