High temperatures, humidity, dust, vibration, temperature, and altitude are harsh environments for power supply applications and must be prepared to overcome these environments. In specialized areas such as rust prevention and wastewater treatment, both high sulfur content and chemicals must be considered. Moisture-proof products can only provide some protection against temperature, humidity, and reduce some device defects. However, in extremely harsh environments and fields where high reliability is required, a dedicated power supply is the most appropriate solution.
OLFER Electronics and MEAN WELL presented a few months ago the HEP series, a power supply designed for harsh environments. It has an IP67 waterproof and dustproof protection, 10G anti-vibration capacity, with a fanless design and a robust aluminum casing filled with a special silicone that conducts heat and insulates electricity and moisture, this allows better dissipation. heat and greater resistance to water. With an innovative design, they have high efficiency to reduce electricity consumption and heat generation. They are ideal for applications where we do not want to use fans and need a robust source. These power supplies are suitable for indoor and outdoor telecommunication and industrial equipment. It also offers different digital communication functions, which can be integrated into human-machine interfaces (HMI) for system control.
HEP-2300 series has charger function for lead-acid batteries and Li-ion batteries. With high efficiency and fanless design. Withstands 10G vibrations and has a wide operating temperature range (-40 to +70ºC). It integrates multiple protections with LED power indicator and remote control for power on-off, as well as DC-OK signal.
The HEP-2300 is specially designed for systems that work outdoors and indoors and require a power of more than 2000W.
This series has up to four different output voltages, 55V /115V /230V and 380V. It is suitable for dusty environments or indoor and outdoor equipment. The output voltage can be adjusted in three ways: via a built-in resistor, via a programmable function (PV/PC) or digital communications such as CAN bus, PMBus and Modbus.
In addition, the HEP-2300 series also provides three wiring methods, such as traditional terminal block, waterproof wiring, and waterproof connector. Specifically, the waterproof connector can be used for 4G RRU (Remote Radio Unit) telecom radio equipment and 5G AAU (Active Antenna Unit) active antennas. It also offers different mounting solutions, such as the types of mounting plate, rear or side mounting.
In addition, HEP-2300 can be used in various outdoor applications, such as cathodic corrosion protection equipment, sewage treatment equipment, outdoor vehicle charging, outdoor communication equipment, and outdoor display screens.
Figure 2 is a diagram showing some practical application examples, which may serve as a reference for similar applications in the future.
