Power Limited 24VAC Supplies
| The National Time PS-3,
PS-6, PS-12 Power Supplies are designed to compliment National Time's Master Clocks with low
voltage digital and/or analog clocks. Each offers power limited transformer(s) with individual
circuit breakers to allow less costly Class 2 wiring installations. Each transformer can supply
3.12A of 24VAC. For 2- wire clock systems, each transformer supports a clock circuit, while for
3-wire systems one transformer supplies 'run' power while another supplies the 'reset' power for a
clock circuit. The power supplies may be converted to Remote Power Boosters with the addition of
the optional PS-Relays. Each power supply is housed in a durable steel enclosure designed to match
National Time's Master Clocks and create an integrated and attractive
installation. PS-3: One 3.12A 120/24VAC Transformer will support one 2-wire clock circuit. Order one PS-Relay to create circuit booster supply. 9"x8"x4" Enclosure. Two knockouts each side. PS-6: Two 3.12A 120/24VAC Transformers will support either two 2-wire clock circuits, or one 3- wire clock circuit. Order one PS-Relay to create a dual circuit 2-wire booster, or two PS-Relays to create a 3- wire circuit booster supply. 9"x8"x4" Enclosure. Two knockouts each side. PS-12: Four 3.12A 120/24VAC Transformers will support either four 2-wire clock circuits, or two 3- wire circuits. Order one PS-Relay to create a quad circuit 2-wire booster, or two PS-Relays to create a dual 3-wire circuit booster supply. 12"x12"x4" Enclosure. Two knockouts top and bottom.
