Power supplies overcome harsh environments

Under free air convection cooling, they can operate at the ambient temperature between -40℃ and +70℃. The unit body is an aluminum case, and the interior is filled with heat conducting silicone so that HEP-600 and HEP-600C can highly reliably work in a high temperature, highly humid, highly dusty, and highly vibrating (withstand 5G vibration) harsh environment. HEP-600 and HEP-600C both accept the full range 90~264VAC input.

HEP-600 provides nine models with different DC voltage between 12V and 54V; HEP-600C, with 3 stage charging curve, provides 14.4V, 28.8V and 57.6V, the three different voltages lead-acid batteries adopt often as charging voltage. Other functions and characteristics include over current protection (HEP-600, constant current limiting mode), short circuit protection, over voltage protection, over temperature protection, built-in 5V standby power, built-in remote ON/OFF control, no load power consumption <0.5W at remote off, and etc.

These series are complied with international regulation such as UL, CUL, TUV, CB, and CE, assuring the safety for usage. Suitable applications for HEP-600 are outdoor telecommunication equipment, signboards, billboards, and humid and dusty industrial control, whereas HEP-600C fit the applications for robotic lawn mowers, electronic transportation vehicles, recreational crafts, security systems, and so on.
