Electrical Features

DC-DC Isolated Power Module MXDA15-25W Series

(Only partial models are listed. Please inquire for other model specifications.)

Note 1: Ripple noise is measured with a 20MHz bandwidth using the parallel-line method.

Note 2: Leakage current test: 5mA for AC voltage, 0.5mA for DC voltage.

Note 3: Additional external recommended circuits or filters are required to meet relevant industry EMI standards.

FUSE: It is recommended to use slow - blow type products. When selecting the FUSE current, the influence of high - temperature derating and inrush current should be considered.

MOV: Varistor. MOV can be used in series with a fuse to prevent MOV failure. Two MOVs can also be connected in series to increase reliability.

C0, C3: High - frequency electrolytic capacitors

C1, C2: High - frequency multilayer ceramic capacitors or film capacitors.

LCM: Common - mode inductor. For specific models, please consult the sales staff.

CY1, CY2: Safety Y2 capacitors

Notes:

1.The values of R1, R2, R3, and Vref refer to Table 1;

2.Rπ is the Trim resistor;

3.a is a custom parameter with no practical meaning;

4.Vo’ is the actually required upward or downward adjustment voltage.

Mechanical Drawing & Pin Definition (Unit: mm)

Module power supplies are widely used in various sectors of social production and daily life, including aerospace, rail vehicles, ships, military weapons, power generation and distribution, postal and telecommunications, metallurgy and mining, automatic control, household appliances, instrumentation, and scientific research experiments. They play an irreplaceable and vital role, particularly in high-reliability and high-technology fields.

HaloCore Control has a complete R&D, production, and testing system. All products are independently developed and manufactured by us.Specialization, Integrity, Innovation, and Agility are our corporate values: stability, high efficiency, safety, full power output, multiple protection functions, with product reliability as our primary goal.

Specialization: Focused on power supplies and solutions, with extensive experience and rich case histories

Integrity: Honest and practical cooperation

Innovation: Smart innovation, leading technology development

Agility: Quick market response and rapid service

We strictly control and manage the entire development and production process in accordance with the ISO9001 quality system standards. Our products have passed international CE and RoHS certifications.

1.It is generally recommended that the long-term operating power does not exceed 70–80% 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.For dual-output power supplies with a common ground, the outputs of both channels must be balanced. Failure to do so may result in output instability.

9.If the load is inductive or capacitive, please confirm the maximum current.
