Intermatic is introducing new auto-voltage, 40-amp defrost timers at the 2011 AHR Expo. The new DTAV40 Mechanical and the DTAV40E Electronic Auto-Voltage Defrost Timers automatically detect the appropriate supply voltage between 120 and 240 VAC, replacing many voltage specific competitive clocks. The auto-voltage feature reduces potential wiring errors and installation time. Both defrost timers are time initiated and temperature, pressure, or time terminated. LED lights indicate defrost or refrigeration cycles.
