Control Panels Integrating all the components – temperature controllers, overtempera- ture controllers and Power Controllers – into standard, off-the-shelf-pan- els, sets Chromalox apart from the competition. Chromalox stocks more standard power control panels, in different sizes and configurations than anyone in the industry. Choose from basic. single-circuit, low amperage contactor or SCR mini control panels to sophisticated, multiple circuit, higher amperage phase angle SCR control with full system diagnostics and several layers of process redundancy. Every panel is pre-engineered, field-proven and ready to install, and saves you the time and trouble of selecting, obtaining and assembling the various components. Select from pre-configured panels that include: • NEMA 12, 7, 4X or 4 Enclosure • 120-690 VAC • 25 Amps - 1200 Amps • Zero Cross or Phase Angle • Process/Temperature Controller(s) • Overtemperature Controller(s) • SCR Power Controller(s) and Fusing • Contactor(s) • Hybrid Contactor with SCR Trim Control • Pushbuttons, Switches, Indicators and Labeling Options • Agency Approvals (UL, CSA, cUL)
