Power Supplies for Testing Mobile Radios

To production test mobile radios, sophisticated equipment is required. Not only does the instrument have to have the capability to generate and analyse a wide frequency range of complex RF signals, it must use low noise power supplies to avoid potential waveform distortion. With space on the production line at a premium, the end product also has to be compact.

A global manufacturer of radio test equipment wanted a supplier that could support a very short time-to-market for a customised power supply. TDK-Lambda’s Power+ Solutions team developed such a product, utilising a suitable platform technology to reduce lead-time.

In addition, TDK-Lambda offers a wide range of standard Industrial Power Supplies for industrial, test and measurement applications, click for more information.

Compact 75Vdc input EMC Filter is rated at 50A

LA006455 - RDEN Filter

TDK Corporation announces the introduction of the RDEN-048050 48Vdc nominal EMC filter rated at 50A. Enclosed in a compact metal case, the filter utilises stud terminals for ease of connection. Excluding the terminals, the filter measures just 90mm in length, 60mm in width and has a height of 30mm.

Rated for a maximum voltage of 75Vdc, the RDEN will operate at full rated current in ambient temperatures of -30 to +55ºC, and with derating, up to +85ºC at 20A. The RDEN has a differential mode attenuation of 25dB (0.7 to 30MHz), and common mode attenuation of 30dB (0.2 to 10MHz). The isolation voltage from terminals to case is 1500Vdc, and has a DC resistance of 3mΩ.

The filter is certified to UL 60950-1, CSA C22.2 No.60950-1 (cUL) and EN 60939, and is compliant with the RoHS Directive.

100A digitally controlled Point Of Load converter is PMBus™ compliant

LA006630 - iJC series

TDK Corporation announces the introduction of the iJC series of 100A Point of Load (POL) non-isolated DC-DC converters with PMBus™ communication. These converters utilise adaptive digital control to deliver improved transient response and system stability across a wide range of output capacitance.

Accepting an 8 to 14Vdc input, the output voltage of the iJC can be adjusted from 0.6 to 1.5V with currents of up to 100A and a maximum output power of 150W. With the current share function, converters can be paralleled to produce 180A, utilising either a PMBus™ command or an external resistor. Weighing just 20g and measuring 28.0 x 35.0 x 10.0mm, these ultra-compact converters are ideally suited for a wide range of applications, including communications, broadcast, industrial and test and measurement equipment.

The read and write functionality of the PMBus™ allows precision, real-time monitoring of the output voltage, current and temperature. The iJC’s operating parameters can also be easily programmed using the TDK-Lambda GUI interface. The converters can be used without the PMBus™ function through the use of function pins.

The iJC series will reliably operate across a wide -40 to +120oC temperature range with minimal airflow, providing a true “useable” power. High efficiency levels are maintained across light to full loads and are as high as 91.5% for a 1.5V output.

Safety certification includes IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.

Constant Current Power Supplies for Battery Charging and Water Purification Systems

Featuring a five-year warranty, the EVS series of 300 and 600W constant current power supplies are suitable for water purification systems or 12V, 24V and 48V battery charging for energy storage. These versatile products can automatically transition from constant voltage to constant current modes, with adjustable settings for different float voltages and charging currents. The 300W is convection cooled and the 600W has a built-in internal fan.

To avoid battery drain, an optional reverse protection module is also available, rated at 20A. The use of a low Rds(on) FET reduces voltage drop and energy loss.
