100W to 600W Power Supply Series Has Five Year Warranty

TDK Corporation announces the introduction of the five year warranty TDK-Lambda RWS-B series of AC-DC power supplies, designed to provide solid performance at an economical price. The product line up has four power levels and compact case sizes, rated at 100, 150, 300 and 600W.

Operating from a universal input of 47-63Hz, 85-265Vac (300Vac for 5 seconds), the RWS-B series is available with nominal outputs of 5, 12, 24 and 48Vdc with an adjustment range of a minimum of +/-10%. The series is designed to meet a wide range of applications, including industrial, test & measurement, broadcast, communications and LED signage.

The convection cooled 100 and 150W models operate from -10oC to 70 oC with derating above 40 oC and the fan cooled 300 and 600W models up to 70 oC with derating above 50oC. In addition over voltage and over current protection is included.

High operating efficiencies of up to 89% reduce internal waste heat and component temperatures, resulting in electrolytic capacitor service life ratings of at least ten years.

The TDK-Lambda RWS-B series is certified to the safety standards of UL/CSA 60950-1, UL508 (on certain models), is CE marked according to the Low Voltage, RoHS2 Directives, and additionally evaluated to EN 60950-1. All models offer curve B conducted and radiated performance to EN55011/EN55022-B, FCC class B and VCCI-B.

More information can be obtained at the following TDK-Lambda Americas website, http://www.us.tdk-lambda.com/lp/products/rwsb-series.htm, or by calling 800-LAMBDA-4.

Powerex QID3320004 Attains UL Recognition

QID3320004 ,manufactured by Powerex, Inc., recently attained UL recognition (E78240).

This Dual IGBT HVIGBT module makes use of the latest Mitsubishi R-Series chip technology, which offers lower losses, a more rugged SWSOA and RRSOA, and a higher current handling capability as compared to previous generations of chip technology.

Highly insulated housings offer enhanced protection by means of greater creepage and strike clearance distance for demanding applications such as medium voltage drives and auxiliary traction.

All components and interconnects are isolated from the heat sinking baseplate, offering simplified system assembly and thermal management.

Product Ratings and Characteristics

This device is rated at 200A/3300V.

Applications

These modules are designed primarily for medium voltage drive applications.

CDE 3-Phase AC Power Harmonic Filter Capacitors

Cornell Dubilier Electronics, Inc. announces availability of its new PFCH capacitor series for 3-phase AC power harmonic filtering. Intended for use on the AC output of large inverter system, Type PFCH are designed to filter undesirable harmonics before power is delivered to the grid or load. Typical applications include but are not limited to automatic power factor correction equipment, wind turbine PFC controllers, solar inverter output filters, tuned and detuned capacitor banks and power line conditioning.

Each PFCH capacitor is made with three self healing metallized polypropylene windings, connected in delta, and enclosed in a cylindrical aluminum case filled with environmentally friendly fluid. Built in bleeder resistors reduce voltage to safe levels when capacitors are taken off line for maintenance. To ensure an open and safe failure mode at end of life, type PFCH capacitors utilize a UL810 tested and approved internal mechanical pressure interrupter that disconnects the capacitor winding from the circuit before pressure exceeds unsafe limits.

Type PFCH ratings range from 0.5 KVAR to 17.5 KVAR at 240 Vac, 0.5 to 30 KVAR at 480 Vac, and 1 KVAR to 25 KVAR at 600 Vac. Standard case sizes range from 2.0 inches to 3.5 inches in diameter with lengths ranging from 5.75 inches to 13.73 inches. Larger case sizes and KVAR ratings are available upon request.

For power factor correction applications not requiring higher harmonic filtering, the company offers Type PFCS with greater KVAR ratings needed to achieve unity power factor correction.

In OEM quantities Type PFCH capacitors are available with pricing from $35. Samples are available in 4–6 weeks, production in 8–10 weeks.
