Altronix EBC48 Installation Manual

Altronix EBC48 external battery charger provides faster charging of back-up batteries for Altronix NetWay Spectrum
models. Working with POE240 or POE360 power supply(ies), it allows to recharge 40AH or larger batteries in under
8 hours.
Input:
• 56VDC input (POE240 or POE360).
Output:
• Charging four (4) 12V batteries in series.
• 2A or 4A selectable operation.
Supervision:
• AC Fail Supervision (form "C" contacts).
• BAT Supervision: indicates Low or missing batteries
(form "C" contacts).
EBC48 should be installed in accordance with the National Electrical Code and all applicable Local Regulations.
1. Mount the EBC48 in the desired location/enclosure (mounting hardware included).
2. Set the EBC48 to the desired output current via SW1(refer to Charging Current Output Selection Table).
3. Connect [+ INP –] terminals of EBC48 to 56VDC output from POE240, POE360 or any 56VDC power supply
which matches the below chart (Charging Current Output Selection Table).
4. Measure output voltage before connecting devices and batteries. This helps avoiding potential damage.
5. Connect device(s) to be powered to [+ OUT –] terminals of EBC48.
Use 18 AWG or larger for all power connections (Battery, DC output).
Use 22 AWG to 18 AWG for power-limited circuits (AC Fail/Low or Missing Battery reporting).
Keep power-limited wiring separate from non power-limited wiring (115VAC 50/60Hz Input,
Battery Wires). Minimum 0.25" spacing must be provided.
CAUTION: Do not touch exposed metal parts.
Shut branch circuit power before installing or servicing equipment.
There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.
6. Connect four (4) 12V lead acid or gel type batteries, connected in series to be charged to the terminals
marked [– BAT +] (Fig. 1).
Please note: the charging current has to be subtracted from the total power supply allowable
output current.
Refer to Charging Current Output Selection Table for available current depending on power supply.
Also note: battery recharge time depends on the battery capacity and charging current.
Using 4A charging current setting will allow to return ~28AH of charge into the appropriate size battery.
Battery performance is dependent on battery specifications from the manufacturer. This includes tempera-
ture ratings, charge capacity, charge/discharge cycles and depth of discharge. Altronix is not responsible
for battery installation methods.
