Product Overview


480 Watts DIN Rail Power Supply  

Available Outputs:   12V,  15V,  24V,  36V,  48Vdc  

Description   The HSE power supply series realizes very high power efficiency in a space-saving housing. This design enables Green Power applications and allows free air convection. 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 our products. The used screw terminals allow easy to wire and smooth service.

Parallel and Serial Operation:   Camtec power supplies of the same model and the same output voltage can be either used parallel or in serial. The assembling of external parts is usually not recommended. Make sure that the output voltage of each connected unit is ±1% equal. We recommend connecting the DC-outputs to a neutral point or a power bar. Follow the safety norms of dangerous dc-voltages. Most of the HSE power supplies allow selecting a parallel operation mode with a switcher B (not HSE01201 & HSE03201). The parallel operation select tilts the C/V-chart a little bit. In result the switching is softer. The power sharing between the units is more accurate. The HSE models can be used floating until 300Vdc (not HSE01201 & HSE03201)

UI-Chart, overload and temperature control characteristic   The HSE models base on a typical resonance forward converter. The devices provide an ideal vertically C/V-chart with no fold back. Thus the converter is ideal for complex loads and DC-drives. Consciously we resigned an excessive power boost that mostly occurs in less exact working control circuits. The advantage is, that the power supply delivers its energy always controlled and constant to the load. Even with a faulty operation of the power supply the loads never expose to high risk. The temperature control follows the C/V-chart. The power will be reduced over the voltage and the current remains constant (CC-mode). If the power supply really overheats the output voltage will be shot down. When the temperature recovers the unit automatically recovers and restarts into normal operation. As a standard the power good relay allows to control the power supply.

Coating Option add 'C' to model number, eg HSE04801.12TC

We offer the HSE optional coating. It is to be used in e.g. dusty, dirty, high humidity, or in awaiting quick temperature changes. Short circuit and corrosion at print board lines and at solder points can be prevented. The coat itself is a transparent acrylic resin. It is procured with a robotics varnishing machine.
