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.
