• Integration into industrial automation and control systems
• Laboratory equipment requiring steady 5V, 12V, and -12V outputs
• Small-scale electronic devices and experimental setups

When it may not be suitable

This device is an open frame power supply, meaning it lacks an enclosed outer casing and is generally not suitable for standalone external use where exposed terminals could pose safety risks. It should also be avoided in applications requiring power outputs significantly higher than the 45 W limit or configurations that do not match the specified triple output voltages.

Key specifications

• Power output: 45 W
• Input voltage range: 90 to 264 V
• Primary output: 12 V
• Additional outputs: 5Vdc at 5A, +12Vdc at 2.5A, -12Vdc at 0.5A
• Design type: Open frame power supply with triple output
• Compliance: RoHS compliant

How to use

Installation should be performed by qualified personnel familiar with open frame power supplies and electrical safety practices. Ensure the input voltage matches the specified range before connecting the wiring to the input terminals. Secure the unit properly within a suitable protective enclosure or housing to prevent accidental contact with live components during operation. Connect the appropriate output lines to your devices according to the required voltage specifications.

What to consider before purchase

• Verify that your equipment requires the specific voltage and current combinations provided by this triple output model
• Ensure you have a secure, enclosed housing or mounting space, as this is an open frame unit
• Check that your total power consumption does not exceed the 45 W capacity

Usage recommendations

Always disconnect the power source before performing any wiring or installation tasks. Ensure adequate ventilation around the unit within its enclosure to prevent heat buildup during continuous operation.
