Product Overview :BDM Series High-efficiency DC Power Supply Module 

In the architecture of industrial automation, intelligent manufacturing, and distributed control systems, a stable and efficient isolated DC power supply is the cornerstone for the reliable operation of all core controllers, sensors, actuators, and communication modules. To address the diverse power supply requirements of on-site equipment and high reliability demands, Chengdu EBYTEE Electronic Technology Co., Ltd. (EBYTEE) officially launched the BDM series industrial-grade isolated DC power supply modules. Through a clear power-voltage matrix design, this series aims to provide engineers with a complete power solution covering mainstream industrial voltage requirements, featuring high-efficiency conversion and safety protection, serving as the "power heart" that drives the stable operation of intelligent devices.
The BDM series is not a single power product, but a standardized product matrix constructed based on three core dimensions: input voltage (wide AC voltage), output power (10W/15W/6W), and output voltage (24V/12V/5V). This design approach transforms power supply selection from "estimation" to "precise positioning".

Analysis of Model Naming Rules:
By analyzing the model list, we can clearly interpret its naming logic: BDM[Form Factor/Size]-[Power]W[Input Voltage]P[Output Voltage]E1

• BDM21 / BDM41: Represent the module's form factor or installation interface specification, which is key to considering physical installation compatibility during selection.

• 10W / 15W / 6W: Refer to the module's rated output power, determining how many devices and what load size it can power.

• 24P: Indicates an AC wide input voltage (AC 85-264V), adapting to global power grid standards and serving as a typical input specification for industrial applications.

• 24E1 / 12E1 / 05E1: Refer to the isolated DC output voltage, corresponding to 24V, 12V, and 5V respectively. This directly matches the core operating voltages of different industrial equipment.

Value of Matrix Design:

• Zero-error Selection: Engineers no longer need to compromise by choosing a "roughly suitable" power supply. They can precisely locate the required model in the matrix based on the operating voltage and total power consumption of the target equipment.

• Simplified Inventory and Spare Parts: Enterprises can standardize the procurement of a few models based on commonly used voltages and power, covering the power supply needs of most equipment and greatly simplifying supply chain management.

• Modular System Design: Subsystems with different voltage requirements can independently select corresponding BDM power modules, realizing modular and standardized design of the power supply system and improving overall reliability and maintainability.

Functional Features: Defining Core Standards for Industrial-grade Power Supplies
While providing a precise parameter matrix, the BDM series power modules also implement industrial-grade standards in performance, safety, and reliability:

Wide-range Input and High-precision Output:

• Global Universal Input: Supports AC 85-264V wide voltage input, adapting to power grid fluctuations and compatible with mains standards in different regions worldwide, ensuring consistent power supply for equipment deployed globally.

• High-precision Voltage Regulation: Adopts advanced switching power supply technology, featuring high output voltage accuracy and low ripple noise, providing "clean" power for backend precision controllers, ADC sampling circuits, etc.

High-efficiency Conversion and Excellent Heat Dissipation:

• High Efficiency and Energy Saving: High conversion efficiency (typical value >85%) means less energy dissipated as heat, not only saving energy but also reducing the module's own temperature rise.

• Excellent Heat Dissipation Design: Metal casing or package design with heat sinks (depending on BDM21/BDM41 form factor) ensures long-term stable operation under full load and high ambient temperatures, meeting strict temperature rise requirements for industrial equipment.

Comprehensive Safety Specifications and Electrical Isolation

• Safety Isolation: Achieves safety isolation of over 3000VAC between input and output. This feature is crucial as it can effectively block surges, lightning strikes, common-mode interference, etc., from the power grid side, protecting expensive backend control equipment from damage and meeting system electrical safety specifications.

• Comprehensive Protection: The module is built-in with over-current protection (OCP), over-voltage protection (OVP), short-circuit protection (SCP), and over-temperature protection (OTP). When any abnormal situation occurs, the module can automatically shut down the output or enter a protection state, preventing fault expansion and achieving self-protection and load protection.

Industrial-grade Reliability and Environmental Adaptability

• Long-life Design: Uses industrial-grade long-life electrolytic capacitors and other components, with a long design life, meeting the requirements of 7x24-hour uninterrupted operation.

• Wide-temperature Operation: Supports a wide operating temperature range of -40°C to +85°C, capable of coping with harsh temperature environments such as outdoor cabinets and factory workshops.

• High Reliability: Excellent EMC performance, able to withstand certain vibration and shock, suitable for complex electromagnetic and environmental scenarios in industry, transportation, etc.

Compact Design and Convenient Installation:

• Compact size, saving valuable space in control cabinets.

• Supports standard DIN rail installation (depending on the specific model), unified with the mainstream installation methods of PLCs, circuit breakers, terminal blocks, and other equipment in industrial sites, facilitating integration and maintenance.

Typical Application Scenarios
The launch of the BDM series power matrix aims to provide a standardized power core for the following fields:

• Factory Automation (FA) Control Cabinets: Provide unified, isolated DC power for cabinet-internal PLCs (commonly 24V), HMI touch screens, I/O modules, sensors (24V/12V), safety relays, etc.

• Process Control and Instrumentation: Provide stable power for field transmitters (two-wire/four-wire), analytical instruments, valve positioners (usually requiring 24V).

• Robotics and Motion Control: Power servo drives, stepper motor controllers, machine vision light sources (often 12V or 24V).

• Communication and Network Infrastructure: Provide reliable power for industrial Ethernet switches, serial servers, wireless APs/gateways (often requiring 12V or 5V).

• Smart Buildings and Security Systems: Power access controllers, network cameras, various detectors.

As the "first link" in industrial automation systems, the reliability of the power supply directly determines the stability of the entire system. EBYTEE's BDM series isolated DC power supply modules, through matrix-based product definition, make power supply selection—a fundamental yet critical task—unprecedentedly clear and precise. It is not just a power conversion device, but an important part of EBYTEE's ability to provide complete solutions from the "perception layer" and "communication layer" to the "power layer" for industrial customers.

Choosing the BDM series means selecting an industrially proven, safe, reliable, and easy-to-integrate "power heart" for your industrial equipment. It ensures that whether your system nodes require 24V, 12V, or 5V, and regardless of power requirements of 6W, 10W, or 15W, they can obtain continuous, stable, and protected energy supply, laying the most solid foundation for the stable operation of upper-layer applications.
