Hitek Power Supply Offers 0-70kV Output Voltage Hitek Power has added an RS232-controlled variant to its XRG70 series of compact, high-voltage power supplies for high-performance analytical and measurement X-ray applications. The XRG70-703 RS232 offers an output-voltage range of 0 to 70kV at 0 to 1mA and maximum output power of 70W. The unit also incorporates a 5.5V DC, 3.5A grounded-filament power supply, part of of Hitek 's range of products designed for use in grounded-cathode applications. The filament supply is automatically controlled by the integral beam-current loop control and the power stage uses a current-fed resonant push-pull converter to give high efficiency while ensuring reliable operation. The product combines surface-mount technology, high-voltage stress control and new packaging techniques. It measures 140 (W) x 73 (H) x 233mm (D) and weighs 3.3kg. The RS232 interface offers remote monitoring of output voltage and current, filament voltage and current, volt...

Power Supplies Provide Constant Voltage Output Powerpax has introduced a range of waterproof IP67-rated power supplies that are particularly suitable for LED applications, as well as CCTV and access security requirements. The CE and UL safety-approved series meet RoHS requirements and start at 15W, providing a constant voltage output in a case measuring 160 x 30 x 20mm. The 200W constant-voltage unit measures 230 x 118 x 60mm. Powerpax offer a branding service for orders of 100 pieces and over and are also able to modify standard units to meet customers' exact requirements, such as custom lead lengths and input and output terminations. Powerpax also offers 15 and 30W constant-current IP67-rated LED units within the same range. All units are housed in a high-quality aluminum case.

Keithley Hosts Capacitance-Voltage Testing Webinar Keithley Instruments will host a 45min online seminar entitled 'Semiconductor Capacitance-Voltage (C-V) Testing Fundamentals'. The seminar will be broadcast on 29 October at 15:00 CET, to enable engineers based in Europe to participate in the live event. The webcast is free to attend, but registration is required. The seminar will introduce the topic of C-V measurements as they relate to semiconductor device and materials characterisation. It is recommended for engineers who are new to semiconductor materials and device testing and those that want to refresh their knowledge of the subject.

Multi-Tone Sounder Has Wide Operating Voltage The SA5 safe area multi-tone sounder from RTK Instruments is said to be a high-specification, cost-effective alarm sounder with a maximum sound output of 112dBA. Ideally suited to areas of high ambient noise, the sounder has an operating voltage of 9-28VDC and low current consumption, making it flexible in operation. The SA5 sounder offers a choice of 32 tones, which are user-selectable using a DIL switch during installation. A second tone is available, which can be switched in by the connection of a third wire to the sounder. The IP65-rated casing provides a high level of durability and resistance to environmental conditions. All connections are made to the base and the sounder head twists and locks into position on commissioning, avoiding wiring and connection problems.

400 Amp 2300-7200 Volts (Medium Voltage) The HCV-5HA, the first vacuum contactor produced in Houston, Texas, was also the first Toshiba vacuum contactor to incorporate an electronic drive unit to power the operating coils. This solid state design eliminated the economizing resistors and improved the reliability of the coil circuit. The contactor is available in either electrically maintained or latched type version. The compact size and high performance, as well as being available in a drawout design, has helped many OEMs and end-users replace old air-break contactors and breakers. Toshiba Offers Superior Features Environment Resistant: Ideal for use in high dust areas. Switching arc is contained within the vacuum bottle, shielding the main contacts. Reduced Maintenance: Vacuum bottle contacts have long life with virtually no maintenance required. No External Surge Protection: Special main contact materials minimize chopping current. No surge suppresser required. Designed f...
