Advantages of Power Module
● Simple Design
A power supply can be realized with just one power module and a few discrete components.
● Shortened Development Cycle
Module power supplies generally offer a variety of input and output options. Users can also stack or cross-connect modules to build modular combined power supplies, achieving multiple inputs and outputs, which significantly reduces prototype development time.
● Flexible Modification
If product design changes are required, simply replace or parallel another suitable power module.
● Low Technical Requirements
Module power supplies typically feature standardized front ends, highly integrated power modules, and other components, making power supply design simpler.
● Good Heat Dissipation
The housing of module power supplies integrates heat sink, radiator, and casing into one structure, enabling conduction cooling and keeping the power supply temperature close to the minimum. At the same time, it gives the module power supply an attractive appearance.
● High Quality and Reliability
Module power supplies are generally produced with fully automated manufacturing and high-tech production techniques, ensuring stable and reliable quality.
● Wide Range of Applications
Module power supplies can be widely used in various fields of social production and daily life, including aerospace, locomotives and ships, military weapons, power generation and distribution, postal and telecommunications, mining and metallurgy, automatic control, household appliances, instrumentation, and scientific research experiments. They play an irreplaceable and important role especially in high-reliability and high-technology fields.
HCD-M Series Power Supply Dimensions

Unit:mm
Multiple isolation methods are adopted between input and output to improve the safety factor of the power supply.
This product uses two isolation methods between input and output:
Isolation Transformer (Magnetic Isolation)
The main function of the isolation transformer is to completely electrically isolate the primary side from the secondary side and isolate the circuit. Using an isolation transformer makes the primary side floating to ground, at which point the system's ground capacitance current is too small to cause harm to the human body. Another important function is to isolate dangerous voltages and protect personal safety.
Optoelectronic Isolation
The main advantages of optoelectronic isolation are: unidirectional signal transmission, complete electrical isolation between input and output ends, no influence of output signal on input end, strong anti-interference ability, stable operation, no contacts, long service life, and high transmission efficiency. In monolithic switching power supplies, linear optocouplers can be used to form optocoupler feedback circuits, achieving precise voltage stabilization by adjusting the control end current to change the duty cycle.

Notice
1.It is generally recommended that the long-term operating power does not exceed 60–80% of the rated power to ensure better service life. Good ventilation is preferred; in poorly ventilated or enclosed environments, a larger power derating margin is required. Terminal-type power supplies should be mounted tightly against the metal casing of the equipment to maximize heat dissipation. Pin-type power supplies require effective ventilation for cooling.
2.Please consider all factors and leave sufficient margin when selecting the power supply.
3.Please inform our customer service of the type of load or equipment connected to the power supply. If the load is inductive or capacitive, please specify clearly, as maximum current must be considered during power selection.
4.The application circuit is for reference only. Customers should make appropriate adjustments and verification based on their actual usage conditions.
5.Due to the specific nature of power supply products, it is recommended to purchase a few units for trial use before full deployment. Thoroughly test whether the power supply meets your requirements. For bulk orders, pricing is negotiable. As we are a self-developed manufacturer, we can offer discounts.
6.For terminal-type power supplies, the adapter base plate is not included by default. Customers requiring the base plate may specify this in their inquiry.Some power supply models do not feature input reverse polarity protection. Please ensure correct wiring during use, clearly identify the positive and negative terminals, and test with a multimeter first. Safety comes first.
7.It is normal for the power supply to generate heat during operation. Under standard conditions, a temperature rise of 20–30°C is perfectly normal. Do not judge the temperature by touch. The casing may become hot during operation and contact could cause burns.
8.Military-grade power supply lead time: 3–7 working days. For specific delivery time, please inquire with your parameters and order quantity.For military-grade power supplies, if customization is required, please confirm the specifications in advance.
9.If the load is inductive or capacitive, please confirm the maximum current.
