Power Supply 60Vdc

Mechanics

Stable metal/aluminium housing IP20. To allow adequate convection, a free air space of 50mm (top/bottom) and 10mm (sidewalls) is required; and for active devices 15mm space from the sidewalls. For proper air convection it is necessary to install the HSE. One can use the DIN-Rail installation (equipped standard) with our patented 35mm DIN-Rail bracket according to EN60715. It is easy to mount/dismount while snaping it onto the 35mm DIN-Rail - no tools necessary.

Design Concept

The HSE power supply series realizes high power in a space-saving housing. Latest generation electrical devices relate to the high reliability. The philosophy is, to employ 125°C low ESR ultra long-life capacitors where expedient to achieve a superior lifetime of the product. The HSE power supply is made for high reliable and demanding industrial applications like galvanic systems, professional DC-drives, UPS-System, and high dynamic load. The power supply is galvanic isolated between the input and the output. All features are connected to the DC power outputs.

Thermal shutdown

The HSE units are 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 HSE units deliver constant current and zero output voltage. They recover automatically after the short circuit is released.

Open Circuit Protection

The HSE 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 have 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.

Current Voltage Chart, CV & CC mode

The HSE series provides a perfect current voltage chart. It has no fold back or other abnormalities. The output voltage can drop down to zero volts when the power supply is overloaded. The unit delivers a stable and constant current to the outputs.

DC-OK (Power Good Relay)

The DC ok relay indicates if the output voltage is low and if the AC voltage is low. The contact is galvanic insulated to the AC input and the DC output connections. The isolation to the AC input is 3000Vac with a forced isolation and covers the overall adjustment range of the HSE models. If the DC voltage is ok the relay is closed, if the power supply unit is in false operation the relay is open. Considering the lower and the upper margin of the AC voltage detection it is to say that the HSE series starts at 85Vac/150Vac depending on the AC input selector. The unit starts with 200Vdc when a DC voltage applies to the input. Make sure to set the AC input selector to 230Vac (factory setting) for DC input supply. DC-Fail hysteresis: drop-out 20% Vnominal / pull-in 60% Vnominal. Contact Rating 30Vdc/1A, 60Vdc/0.3A, 30Vac/0.5A

Relay indication:

Normal condition: Relay closed

- Over temperature: Relay open

- AC Low voltage: Relay open

- DC low voltage: Relay open
