150W Dual Output Isolated DC-DC Converter for Industrial Robot Control Systems

Why Do Industrial Robots Experience Controller Resets, Camera Dropouts or Safety Module Alarms?

When an industrial robot stops unexpectedly, loses camera communication or reports a safety-system alarm, engineers usually inspect the robot program, fieldbus network, servo drives and sensors first.

However, unstable auxiliary power is often the hidden cause.

Industrial robot systems commonly contain both 24V loads—such as safety controllers, I/O modules, relays and communication devices—and 12V loads such as industrial cameras, displays or embedded terminals. Voltage fluctuations and electrical noise generated during servo acceleration, braking and load changes can affect both rails, resulting in controller resets, communication failures, false alarms or unplanned robot shutdowns.

Root Cause Analysis

Typical engineering challenges include:

Voltage sag caused by servo startup and dynamic robot movement;
Different voltage requirements inside one robotic system;
EMI generated by servo drives, motors and power cables;
Additional wiring and failure points from separate power supplies;
Limited cabinet space and restricted airflow;
Continuous production requiring high power reliability.

The real challenge is not simply converting voltage. It is maintaining stable, isolated power for multiple sensitive robot subsystems.

Engineering Requirements

Engineers need a power solution that can:

Provide regulated 12VDC and 24VDC outputs simultaneously;
Operate from a fluctuating industrial 24V bus;
Reduce power-module count and wiring complexity;
Isolate sensitive control circuits from power-side noise;
Operate without fan maintenance;
Protect downstream devices during abnormal conditions.
How MINGZINC Solves the Problem

The MDB150-24D12&24 accepts a wide 18–36VDC input and simultaneously provides 12VDC/4A and 24VDC/4.16A outputs.

The 24V rail can support robot safety controllers, Remote I/O, communication modules, relays and compatible brake-control devices. The 12V rail can power industrial cameras, displays and embedded control terminals.

By supplying both voltage rails from one converter, the module reduces component count, cabinet wiring and installation space while simplifying auxiliary power distribution.

Input-to-output galvanic isolation helps prevent servo-drive noise and ground interference from reaching sensitive control electronics. Natural cooling eliminates fan-related maintenance, while undervoltage, overvoltage, overtemperature, overcurrent and short-circuit protection improve system safety.

Why MINGZINC?

MINGZINC evaluates robotic power systems based on actual loads, startup conditions, cabinet space, thermal requirements and integration needs—not voltage ratings alone.
