Rotary Drive Synchronous (RDS)
NATIONAL TIME is pleased to reintroduce the synchronous time system with today's high tech performance! Microprocessor technology has replaced the slow, troublesome spring/ratchet/solenoid engagement designs currently offered by other manufacturers. National's revolutionary Rotary Drive time system can instantly correct all of the building clocks to the exact hour and minute at any time of the day! With our on demand instant time correction, you no longer have to wait up to twelve hours or perform confusing, tedious sequences of manual stops, starts and resets. We give you the correct time when you need it --- NOW!
For systems not incorporating the National MC100, On-Demand correction may be achieved using the PS-3-OD Power supply or URTOD- HH module. Rotary Drive guarantees to outperform all existing clock technology without sacrificing the unsurpassed durability you have come to expect from National Time's synchronous motor drive systems. The 3WS series will emulate most existing synchronous clock operation without the frailties of solenoids, ratchets, switches or levers. See Compatibility List bulletin C-430. Each clock is equipped with an all metal case, convex glass crystal, and white polystyrene dial having black markings and hands. A sway-proof hanger plate is furnished that securely holds clock to wall. Cases are attractively finished in Powder Gray enamel. Other finishes and shatterproof lens are available upon request. Shatterproof lens now standard on 12” round.
