AMETEK Programmable Power has added the ability to sink DC current to its California Instruments' RS and MX Series Power Sources. The addition of this option to an RS or MX Series power source with AC Sink installed allows users to source and sink both AC and DC currents at up to 100 percent of the source's rated output power. When sinking current, the current is regenerated and returned to the electrical grid reducing the operating cost of electricity.
There are many applications for sinking AC current, such as the prevalent need to regenerate current back to the electrical grid while testing grid-tied inverters. A common DC sink application, among others, is to simulate batteries connected to a bidirectional converter in hybrid electric vehicle motor drive systems.
When purchasing a new RS or MX Series power source, customers can purchase the SNK option to sink only AC current, the SNK-DC option to sink only DC current, or both options for ultimate versatility. Upgrading an existing RS unit can be done by AMETEK, depending on the age of the unit. Consult factory for further details.
