Description   The HSEUREG laboratory power supplies provide low noise and ripple, a very quick programming, and an absolutely precise setting at high load changes. With an efficiency up to 90% the devices are highly energy efficient. Equipped with high-end capacitors of outstanding lifetime our power supplies guarantee a very long and reliable operation time. The circuit design of the HSEUREG Series allows cope playing with complex loads. The internal protection circuits protect the power supply and the connected system, even in exceptional situations. The HSEUREG series is protected from high transients by strong filters with high energy efficiency. All inputs and outputs and the interface are electrically isolated. The design specifications call for the highest standards of safety and interference suppression. The device was developed in accordance with the requirements of IEC/CSA/UL60950-1 and the EMC standards EN55022 Class B. The 480W and 720W models provide natural convection. The 1kW models use a forced air cooling system with a two stages fan

Design Conception   The HSEUREG power supply series realizes high programmable power in a space-saving housing. Latest generation electrical devices relate to the high reliability of all CAMTEC products. The CAMTEC philosophy is, to employ 125°C low ESR ultra long life capacitors where expedient to achieve a superior lifetime of the product. The HSEUREG power supply is made for high reliable and demanding industrial applications like galvanic systems, professional DC-drives, and complex test benches

Control type   The power supplies accurately works down low output voltages down to 0V. Thereby the switching frequency is absolute stabile. The output response is linear to the input signal.

Power Good Relay:   As a standard the power good relay allows to control the power supply is ok. When the output voltage breaks down the contact opens. Galvanic isolation 60vdc..

Programming Performance   THE HSEUREG power supply is very equal to a typical laboratory power supply – just without its displays. It is designed for automated industrial test benches in a 24/7 operation. The HSEUREG provides save and precise down to zero voltage programming. The product is equipped with a multi-functional interface. Thus the interface can be operated with either 0- 10Vdc/20mA or with 0-20mA programming. The burden is 500Ω to ensure interference free operation with high impedance controller interfaces. The device features a small latency and a quick all rise time that leads to typical 15ms from zero to Umax programming.

Galvanic Isolation   The power supply is galvanic isolated between the input and the output. All features like the Power Good Relay are connected to the DC power outputs.

Thermal shutdown   The HSEUREG is featured with a thermal overload shut down and auto recovery behaviour.

Over Voltage Protection   Ticker mode and auto recovery

Short Circuit Protection   A continuous short circuit does not cause damage to the power supply. The HSEUREG delivers constant current and zero output voltage. It recovers automatically after the short circuit is released.

Open Circuit Protection   The HSEUREG series is continuously open circuit protected. The device delivers a stable output voltage and no current. If a load is immediately connected to the device, the power supply stabilizes within 1ms. It does not overshoot the output voltage.

Power Up Ramp   The devices has a soft start ramp when powering up. The device does not either overshoot the voltage nor does the output flutter – independent if a load is connected or not.
