DC Supplies Empower Industrial Control Apps August 2005 Issue Published Date: August 11, 2005
Targeting just about any industrial control application, the 787 series dc-power supplies come in DIN-mount, metal-clad housings that are highly resistant to shock. The primary switch-mode supplies are available in single- or three-phase versions with input voltages of 90 to 264 Vac or 325 to 550 Vac, output voltages of 12 or 24 Vdc, current ratings of 1.3A, 2A, 2.5A, 4A, 8A, 10A, or 20A, and power ratings up to 480W. The units offer high efficiency, over-voltage protection, short-circuit protection, surge protection, and in-rush current limiting via an NTC resistor to ensure operational reliability. Other features include output LEDs, parallel output circuits to increase output current, adjustable output voltages, and analog interfaces for compiling output measurements. Additionally, the series employs Multi Connection System connectors with the company’s CAGE CLAMP technology. Prices start at $81.70 each. WAGO CORP., Germantown, WI. (800) 346-7245.
