Version 1.0
•
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.
