• -30°C to +70°C operating temperature range, subject to derating
• 4,000V AC input-to-output dielectric strength
• Remote voltage compensation
• Optional remote output ON/OFF control
• Short-circuit, overvoltage, overload and overtemperature protection
• LED indicator for operation status
• 3-year manufacturer’s warranty

The combination of high efficiency, flexible output options and fanless operation makes the series a strong choice for engineers developing industrial electronic systems.

Fanless Cooling Without Compromising Performance

Managing heat is an important part of selecting an industrial AC/DC power supply, particularly in equipment that operates for extended periods.

The 64CHA-750 Series uses a fanless, conduction-cooled design that transfers heat through its metal enclosure to an external mounting surface.

Removing the need for an internal cooling fan reduces mechanical components and eliminates fan-generated noise. This can be particularly useful in industrial control cabinets, electronic instruments and equipment where maintenance access is limited.

The series achieves up to 95% efficiency at 230V AC, helping to reduce energy losses and the amount of heat generated during operation.

To achieve the specified thermal performance, the unit must be securely mounted to a suitable aluminium plate or metal housing using thermal grease.

Engineers should review the relevant derating curves when assessing available output under different input voltages, ambient temperatures and mounting conditions.

Wide Input Range and Flexible DC Outputs

Industrial equipment can operate across different electrical environments, making input flexibility an important consideration during product development.

The 64CHA-750 Series accepts 90–264V AC or 120–370V DC, providing engineers with a broad input range for different system requirements.

Five nominal output voltage options are specified across the range:

Each model offers adjustable output voltage, giving engineers additional flexibility when matching the supply to their equipment.

The range supports different industrial voltage requirements without changing the overall enclosure format.

Model availability should be confirmed, as the manufacturer identifies the 12V, 36V, 48V and 55V versions as under development.

Active PFC and Reliable Output Control

The 64CHA-750 Series incorporates active Power Factor Correction (PFC), achieving a typical power factor of 0.95 at 230V AC and 0.96 at 115V AC under full-load conditions.

This helps improve how efficiently the supply draws electrical energy from the AC input.

The series provides several useful control and monitoring functions.

Remote voltage compensation helps account for voltage drops between the supply and the connected load, supporting more consistent voltage delivery. The specified maximum compensation is 0.2V.

Optional remote ON/OFF control allows external circuitry to enable or disable the output without disconnecting the main input supply.

A DC OK signal provides an indication of output status, making it useful for equipment monitoring and control systems.

These features give engineers greater flexibility when integrating the supply into industrial equipment.

Protection Features for Industrial Equipment

Electrical faults can interrupt equipment operation and place additional stress on connected components.

The 64CHA-750 Series includes several built-in protection functions to help manage common fault conditions.

• Short-Circuit Protection (SCP): Protects the output during a short circuit, with automatic recovery once the fault is cleared.
• Overvoltage Protection (OVP): Responds to excessive output voltage and returns to normal operation once the fault is removed.
• Overload Protection (OLP): Uses hiccup-mode protection when the load exceeds the specified limits, with automatic recovery.
• Overtemperature Protection (OTP): Shuts down the output when the temperature protection activates, then restores operation once the fault is cleared.

These safeguards support dependable operation in industrial applications where electrical loads and operating conditions can vary.

Safety and EMC Standards

Safety and electromagnetic compatibility are important factors when selecting an AC/DC supply for industrial equipment.

The 64CHA-750 Series datasheet lists the following safety standards and regional approvals:

• UL 62368-1
• CAN/CSA C22.2 No. 62368-1:19
• IEC 62368-1
• EN 62368-1
• GB 4943.1
• CE, UL/cUL, CB and CCC

The series is specified against EN 55032 Class B for conducted and radiated emissions, alongside FCC Part 15 Class B requirements.

Further EMC specifications include EN 61000-3-2, EN 61000-3-3 and immunity tests within the EN 61000-4 series.

With 4,000V AC input-to-output dielectric strength, the range provides a defined isolation characteristic for engineers assessing electrical safety requirements.

As with any component-level supply, final equipment compliance must be assessed within the complete system.

Applications for the 64CHA-750 Series

The 64CHA-750 Series is intended for industrial equipment requiring high-output AC/DC conversion and effective thermal management.

Potential applications include:

• Industrial Control Systems: Providing DC output for industrial control equipment and associated electronics.
• Industrial Automation: Supporting automated machinery, control equipment and electrical systems.
• Electronic Instruments: Supplying regulated DC voltage to industrial electronic instruments.
• Mechanical and Electrical Equipment: Integrating into machinery and electrical assemblies requiring a high-output enclosed supply.
• Industrial Equipment Cabinets: Supporting installations where fanless cooling and controlled heat dissipation are important.

Its wide input range, output selection and control functions make the series suitable for consideration across a variety of industrial designs.
