COMPACT POWER CENTER (CPC)
COMPACT POWER CENTER (7 KW-CPC)
Development of the CPC system is the summation of several years worth of research & design, collaboration and negotiation with : Spectral Technologies- Toronto Canada Saft- Corporate and Jacksonville Florida plant Crim Engineering and Sales- Birmingham Alabama Southern Company Technical Services Electrical Design
• Energy Source for remote loads
• capable of providing seven (7KW) loads for two (2) hours on battery reserve.
• Load types are 5kW inverter (120VAC Loads ) and 2KW (125VDC) loads.
AC Distribution Panel– 118-122Vac from no load to full load DC Distribution Panel– 100 – 140Vdc from no load to full load. • Unit is to be equipped with an electrostatic shielded
transformer for the dual AC inputs and Inverter Bypass.
Integrated and centralized power unit, with AC & DC distribution centers incorporating an energy source capable of providing seven (7kW) loads for two (2) hours. Load Needs
AC: ~ 5kW via inverter for DCS/DAS DC: ~ 2kW for switch gear loads
