As 5G applications become increasingly prevalent, telephone companies are also dedicated to deploying 5G small cells to improve network coverage as well as communication quality, even portable 5G base stations are used in some large-scale events.

These pieces of telecom equipment also require a power supply to drive. Moreover, they are often installed outdoors or in some harsh environments, shown as in Figure 1. As a result, the harsh environment power supply - HEP series - is suggested.

The HEP series is a specific power supply designed for harsh environments. With IP67 waterproof and dustproof protection, 10G anti-vibration capability, fanless design and an aluminium extruded case for conduction cooling, the power supply series is suitable for use with a variety of outdoor industrial and telecommunication equipment. It also provides a variety of digital communication functions, which can be integrated into human-machine interfaces for system control.
The HEP-2300 is completely perfect for the new generation base stations as the power requirement increased to above 2,000W.
The series includes four different output voltages, 55V/115V/230V and 380V. It is suitable for high dust environments or indoor and outdoor equipment. The output voltage can be adjusted in three ways, a built-in variable resistor, the programmable (PV/PC) function and through digital communication such as CAN bus, PMBus and Modbus, which is convenient for system integration and control through the human-machine interface.
Aside from offering different output voltages, the HEP-2300 series also provides three wiring methods, including traditional terminal block, waterproof wiring cable and waterproof connector. In particular, the waterproof connector can be used for 4G telecommunication radio equipment RRU (Remote Radio Unit) and 5G active antenna AAU (Active Antenna Unit) which can be used in outdoor base stations. It also provides different mounting solutions such as mounting plate type, rear mount or side mount types.
