2. Product Description
The Alpha Modular Power System (AMPS HP2) is a unique, high performance AC and hybrid AC/DC power
system that is ideally suited to provide highly reliable back-up power to cable headend, telecom or server room
facilities.
The AMPS HP2 features hot swappable 2.5 kVA/2.0 kW inverter modules and optional 2.4 kW rectifier modules
