Follow on Google News | New Yorker Electronics Supplies Space-Saving, Direct Water-Cooled Power Wirewound ResistorVishay's DCRF Eliminates the Need for Heatsinks and Handles Almost 10x the Power of Naturally-Cooled Resistors in the Same Size
By providing direct liquid cooling without the need for a heatsink and multiple resistances, the Vishay MCB device also saves on assembly costs. The WCR makes a direct connection to the water circuit per G3/8 female for easy cooling system connections. The Vishay Direct Water-Cooled Power Wirewound Resistor is optimized as a snubber and DC grading resistor for large drives, high voltage inverters, rectifiers and HVDC (High Voltage Direct Current) transmission systems / SVC (Static Var Compensators) The WCR offers very high power dissipation up to 2500W at 60°C water inlet temperature and tolerates high pulses up to 5000W for 10s. It features a resistance range from 4.7Ω to 56kΩ with a ±5% tolerance, a temperature coefficient of 100ppm/°C, and a maximum working voltage to 3500V, with 6600V available upon request. The RoHS-compliant device offers a non-inductive option below 250nH and operates over a temperature range of -55°C to +120°C. Typical applications for the device include Snubber, Permanent Discharge, Balancing and Filtering. New Yorker electronics also offers the option for multiple resistors. Features & Benefits: • Very high power dissipation up to 9000W • High overload capacity (2x nominal power for 60s) • Customization upon request • Compact modular design • Easy to mount and connect • Direct cooling without heatsink • Excellent power / volume ratio • Multi resistive element option Applications: • High power snubber resistor for large drives and HVDC • Filter resistor for large drives • Fast discharge for battery banks (solar) New Yorker Electronics is a franchise distributor for Vishay and supplies its full line of discrete semiconductors (diodes, MOSFETs and infrared optoelectronics) New Yorker Electronics is a certified authorized distributor of electronic components, well known for its full product lines, large inventories and competitive pricing since 1948.
