Aux Display - NE830A (Optional)
The Aux Display is a voltage monitor that alarms when the voltage of the power system is out of the normal operating
range. It is mounted on the door of the distribution box.
Figure 5 NE830 Display
•
Fully independent of the main system controller
•
Displays one or two system voltages and battery state:
•
Single voltage systems, -48V, +24V
•
Dual voltage systems, -48V and +24V with common return
•
The display and LED color indicates battery charge state and wiring errors:
•
Green display
= batteries are not discharging
•
Red display = batteries are discharging
•
Amber display = wiring error
•
A Battery on Discharge alarm relay with form-C contacts is provided
•
Can be panel, wall or frame rail mounted within 150 ft. of the power system
Rectifiers and Converters
NE-Series rectifiers and converters are hot-pluggable for quick, simple, plug-and-play installation without tools.
