Relec adds Cotek AEK 3000 HV Series

A flexible, adaptable range of high voltage DC power supplies has been added to the products available from Relec Electronics.

The AEK 3000 HV Series can be used for numerous applications, including undersea power lines and tethered drones.

The 3kW high voltage (HV) DC power supplies manufactured by Cotek, offer 90 to 264V AC input and a choice of regulated, single outputs (150, 200, 250, 300, and 400V DC). An auxiliary output is selectable from +5V/0.5A or +9V/0.3A.

The high efficiency AC/DC converters are supplied in fully enclosed cases, with integrated fans for cooling operation. They are suitable for use in space-limited applications, having dimensions of just 280 x 170 x 64mm.

Models in the series have built-in redundancy and an ambient operating temperature range of 20 to +60 degrees C. I2C and RS485 communication interfaces, analogue control and programmable output/current (from 0 to 105%) are also included in the feature list. Output voltage and current limit can be controlled via a case-mounted potentiometer, 0 to 5.0V control voltage or via I2C programming. The I2C commands can be used to both interrogate and program the power supply in real time.

The AEK 3000 HV Series models can also read values, such as output voltage, current and internal temperature in real time, as well as monitor alarms for fan failure, over-voltage and high temperatures. These characteristics make the converters suitable for live feedback systems in medical, hi-rel and other space-limited applications where reliability is critical.

The AC/DC converters also feature integral active PFC and a built-in Oring diode.

The wide range of features makes the AEK 3000 HV Series power supplies suitable for challenging and diverse applications, where a chassis-mounted AC-DC converter with high DC output is required in space-constrained applications. Target applications include undersea power lines and tethered drones, medical imaging and charging vehicle batteries, factory automation and off-site test and measurement.

The reliable AC/DC converters are certified to EN/UL62368-1, for A/V information, communication and technology equipment safety, and EN55032, for EMC.

All models in the AEK 3000 HV Series are covered by a three-year warranty.
