Power supply unit ERNITEC ELECTRA-PWR-75-24, model ELECTRA-PWR-75-24

ERNITEC ELECTRA-PWR-75-24 is a compact DIN-rail power supply that provides a stable 24 V DC output for industrial and surveillance equipment. Designed for installation on TS-35/7.5 or 15 DIN rails, the unit accepts universal 100–240 V AC input and delivers reliable low-voltage power for devices such as cameras, access control modules and other 24 V systems used in harsh environments.

Advantages

The power supply features a compact form factor for space-efficient mounting and uses free-air convection cooling to maintain operating temperature without fans. It includes protection against short circuit, overload, over voltage and over temperature to ensure continuous operation of connected equipment. The unit is built to meet industrial EMC and safety standards and is fully burn-in tested at full load for reliability.

Suitable for

• Powering surveillance cameras and video equipment
• Supplying access control modules and door systems
• Providing 24 V power for industrial sensors and controllers
• Use in control cabinets and DIN-rail installations in industrial environments

Key specifications

• Input voltage: 100–240 V AC (universal)
• Output voltage: 24 V DC
• Mounting: DIN rail TS-35/7.5 or 15
• Cooling method: free-air convection (fanless)
• Protections: short circuit, overload, over voltage, over temperature
• Operating temperature range: -20 °C to 70 °C (maximum)

How to use

Install the unit on a compatible TS-35 DIN rail and connect the AC input to a suitable 100–240 V supply following local electrical codes. Connect the 24 V DC output to the device(s) requiring power, observing correct polarity and total load limits. Ensure adequate ventilation around the unit to allow for natural convection cooling and avoid mounting next to heat sources.

Recommendations

Place the power supply inside an electrical enclosure when used in dusty or wet environments, verify connections before applying mains power, and size the load to remain within the unit’s rated capacity for continuous operation.
