Product Description

Product introduction


ACME28 series of aviation military high-power regulated DC power supply using international advanced wide-range ZVZCS soft switch inversion technology, with Germany's Siemens IGBT amorphous core as the core device developed for aviation-military equipment, this series of power supply provides a highly stable output voltage and current, can be applied to plane around the world and the aircraft, can be applied to the start-up power supply of military equipment such as armored weapons, or as an analog experiment for the input power supply of aviation equipment. Because it uses the current international advanced soft switch technology and mature and reliable control circuit, through many years technical accumulation and continuous innovation development and design, the ACME28 has a high accuracy, high stability and high reliability of excellent electronic characteristics in the field of aviation military applications and time and time again written brilliant.
 

1. Meet the requirements of China's national military standard GJB572-88 "Aircraft ground power supply characteristics and general requirements"
2. Meet the requirements of China's national military standard GJB 181A-2003 Aircraft Power Supply Features
3. Compliance with civil aviation industry standardMH/T 6018-1999 Ground static power supply requirements
4. Many specifications

The output voltage is 28.5V, the output current is 50 to 2000A

1. Five new

New electronic components, new electromagnetic materials, new transformation technologies, new control theories, new functions

1. Five highs

High frequency, high efficiency, high power density, high power factor and high reliability   

1. High-precision, low ripple

The DC power supply is controlled by peak current, with fast response and high output regulator accuracy. At the same time, the output is equipped with a multi-stage filter, EMI/EMC meets EN61000-6-3, EN61000-6-1, and the output ripple is low.

1. High efficiency

A wide range of soft switch technology enables high power supply efficiency and low noise, and the efficiency of the entire machine is up to 95% (under load of 100%).

1. Small size and light weight

Due to the use of soft switch transformation technology, the internal radiator is greatly reduced, the whole machine volume than the hard switch regulated power supply is smaller and more reliable, lighter weight, high power density, can meet the special needs of many military equipment.

1. High reliability

With input phase-out protection, short-circuit protection, overload protection, overvoltage protection, overcurrent protection and independent temperature detection protection circuits and special design for high reliability of military power supplies.

1. Far-end measurement

The far-end measurement function can be used to compensate for the voltage drop between the output terminal and the load.

1. OVP overvoltage protection

The OVP overvoltage protection function is standard and any value srated from 3V to 110% can be pre-set as the PROTECTION value of OVP.

1. Short-circuit protection

A long short circuit is allowed under certain conditions.

1. Overload protection

The power supply has an overload protection circuit inside to prevent damage to the power supply due to overload.

1. Overheat protection

Automatic shutdown with no output when the power supply is overheated, and the device automatically resumes output at low temperatures.

1. Output display

Voltage and current are displayed using high-precision LED digital meters.

1. Intelligent

Can be connected to the computer, forming a computer-controlled intelligent power supply (optional).
