Product Features and Benefits:
IMPROVES PROCESS CONTROL: Large (.56" high), easy to read LED display. Two set points (heating and cooling). Provides precise control for consistent plating and etch rates in most aqueous processes.TEMPERATURE SENSOR: Fluoropolymer (FEP) covered 10-foot (3m), 1000-ohm platinum RTD sensor included standard with the control. Provides extended service in corrosive liquids and can be lengthened with ordinary copper hookup wire.
CORROSION RESISTANT ENCLOSURE: NEMA 1, IP23, gasketed plastic enclosure with sealed tactile switches and stainless steel hardware.
CERTIFICATIONS: cUL.
CAPACITIES:
• Large switching capacities from 30 to 150 amps for either 240 or 480 volts (other voltages available). • Single pole, double throw switch rated at 2 amps for cooling loads. • Adjustable temperature range from -40°F (-40°C) to 999°F (538°C). • +/- .25% full span, single digit accuracy. • 20°F (-7°C) to 130°F (54°C) ambient temperature range. • Programmable standby temperature setting for overnight control and energy savings. • 120, 208, 380, 415, 600 and other voltages available. • Single or three phase.
• Control transformer required above 240 volts and recommended for 208 and 240 volt service.
SAFETY FEATURES:
