Master Plus UPS Installation

UPS project recently completed with parallel Master Plus UPS’s, each with two parallel strings of 10 year design life front access sealed lead acid batteries to provide each UPS with 6 hours autonomy at full load. A wall mounted external manual bypass switch (EMBS) allows for bypassing the parallel UPS’s seamlessly or isolating either UPS for maintenance. The EMBS is also fitted with a load bank connection socket.

Site acceptance tests (SAT’s) incorporating power disturbance monitoring, thermal imaging and a full battery discharge test on each system were also performed.
