The MCS16-20SB Indoor Power Supply from Pelco consists of 16 multi-output 24 VAC indoor power supplies. The power supplies allow for 120 or 240 VAC line input. Each output features its own LED power indicator and three-position switch. The switch lets you individually turn off each output or quickly select between 24 and 28 VAC without reconnecting wires. The MCS16-20SB is available with either glass fuses or self-resetting circuit breakers.
