PERFORMANCE SPECIFICATIONS
Power:
24 Vac with a minimum of 20 Vac and a maximum of 30 Vac at
either 50 or 60 Hz. The W7750A power consumption is 6 VA
maximum at 50 or 60 Hz. The W7750B,C power consumption
is 12 VA maximum at 50 or 60 Hz.The W7750A,B,C is a NEC
Class 2 rated device. This listing imposes limits on the amount
of power the product can consume or directly control to a total
of 100 VA.

Special Note for the W7750B,C Unit:
The individual Triac outputs incorporate an internal common
connection with the input power transformer. The Triacs
provide a switched path from the hot side (R) of the
transformer through the load to the common of the
transformer. The W7750B,C Controller design must use the
same power transformer for any loads connected to that
controller; see Fig. 30.

Each individual Triac is rated 1A at 30 Vac maximum. Under
all operating conditions, the maximum load/source power
budget for the W7750B,C Controller is 100 VA. Actual
allowable Triac current is 500 mA MAX.
