Introduction
The 1050/1550 family of COTS AC-source battery chargers (BCA) and power supplies (PWS) 
are designed to supply a DC load or charge a battery at 12, 24, 32, 36, 48 or 72 (Rail) VDC. The 
1050 family provides up to 1000 watts of precision power, while the 1550 family can supply 
up to 1550 watts. These 1050 and 1550 families are identical to their previous models (1005 
and 1505, respectively) in form, t, and function and is a direct drop in replacement for their 
predecessors.
Internally, the recently updated design incorporates a brand new Power Factor Corrected (PFC) 
Input Stage. The PFC input stage increases the efciency over the previous auto-switching 
technology and eliminates the dead spot between 110 and 220 VAC input allowing the power 
supply to run continuously from 90 – 264 VAC In at 45 – 65 Hz. Additionally, heavy input and 
output ltering reduce EMI to extremely low levels to prevent radio interference. 
These units are constructed from heavy-duty anodized extruded and billet machined aluminum 
and all stainless steel fasteners for rugged duty. These units feature a variety of optional 
environmental upgrades including IP66 rated construction for service in marine environments 
(IP67-rated construction with certication and testing also available). Additionally military 
ruggedization upgrades are also available including MIL-spec connectors, expanded operating 
temperature and shock and vibration protection. 
Reliability features include an LED status indicator panel, input circuit breaker, thermal 
shutdown, current limiting, reverse polarity connection protection and output short circuit 
shutdown with automatic recovery.
