October 31, 2011

Continental Control SystemsContinental Control Systems has released its Accu-CT ™ high-accuracy split-core current transformer. Engineered for use with any of the company's WattNode®energy meters, the Accu-CT offers an unprecedented 0.2 percent linearity over a wide range of the rated current (1% to 100% of rated current). V

“If you’re looking for a cost effective, revenue-grade metering solution , we’ve got it with the Accu-CT,” said Cynthia A. Boyd, director of sales for Continental Control Systems. “The performance of this new current transformer is outstanding. The Accu-CT has a distinctive design and color that make it easy to identify a high-accuracy, revenue-grade installation. We’ve also designed in a unique latching mechanism to ensure safe single-handed installation.”

Designed specifically for revenue-grade requirements, the Accu-CT complies with the ARRA (American Recovery and Reinvestment Act) and will provide for ANSI C12.1 accuracy requirements for the California Solar Initiative (CSI) (listing pending) and for ANSI C12.20 (0.5% accuracy) for tenant submetering and billing when used with a WattNode energy meter. Its low-voltage rating/operation (0.333Vac output at rated current) allows for installation without a shorting block.

The UL-recognized and CE-marked current transformer is available in rated currents of 5A, 20A, 50A, 100A, 200A, and 250A, with inside dimensions of 0.75 in. by 0.75 in. (20 mm by 20 mm). The device features 8-ft 22AWG twisted-pair leads.
