By land, by sea, by air: the AEK 3000 HV Series offers flexible high voltage DC power, according to Relec Electronics. Its numerous applications include undersea power lines and tethered drones. The 3kW high voltage (HV) DC power supplies manufactured by Cotek, are now available from power conversion specialist, Relec Electronics.

The flexible AEK 3000 HV Series offers 90 to 264Vac input and a choice of regulated, single outputs (150, 200, 250, 300, and 400Vdc). 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 in space-limited applications. Dimensions are just 280x170x64mm.

Models in the series have built-in redundancy and an ambient operating temperature range of 20 to +60°C. Also included are I2C and RS485 communication interfaces, analogue control and programmable output/current (from 0 to 105%). Output voltage and current limit can be accurately controlled via a case-mounted potentiometer, zero to five volt control voltage or via I2C programming.

The I2C commands can be used to both interrogate and program the power supply in real-time. The capability to 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, make the AEK-3000-HV Series ideal for live feedback systems in medical, hi-rel and other applications where reliability is critical, despite limited available space.

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, as well as medical imaging and charging vehicle batteries. They are also ideal for factory automation and off-site test & measurement.

The reliable power supplies 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.
