Atlas Copco 8433 0005 10 Power Supply Module

The Atlas Copco 8433 0005 10 (part number 8433000510) is a high‑quality regulated power supply module designed to deliver stable 24 VDC to Atlas Copco tightening controllers, interface modules, and auxiliary devices. This unit ensures clean, noise‑free power, which is essential for precision electronics and sensor circuits. Its compact DIN‑rail form factor and wide input voltage range make it suitable for global industrial applications.

Power Specifications

The module converts an input of 85‑264 VAC (47‑63 Hz) or 120‑370 VDC into a regulated 24 VDC output with a rated current of 5 A (120 W). It features active power factor correction (PFC) to minimise harmonic distortion and improve energy efficiency, typically achieving > 90% efficiency at full load. Output voltage adjustment is possible within a ±10% range via a built‑in potentiometer.

Protection Features

Comprehensive protection safeguards both the power supply and connected loads. The unit includes:

• Overload protection (current limiting with automatic recovery)

• Short‑circuit protection (hiccup mode)

• Overvoltage protection (crowbar circuit, shuts down output)

• Overtemperature protection (thermal shutdown with hysteresis)

• Input transient suppression (MOV and fuse)

Mechanical and Environmental Data

• Housing: Metal enclosure, ventilated

• Dimensions: 125 x 100 x 55 mm (W x H x D)

• Mounting: DIN‑rail (TS35) or panel

• Weight: 0.8 kg

• Operating Temperature: -20 °C to +70 °C (derating above 50 °C)

• Storage Temperature: -40 °C to +85 °C

• Humidity: 5‑95% RH, non‑condensing

• Protection Class: IP20

LED Indication and Monitoring

A dual‑colour LED on the front panel shows operational status: green for normal output, orange for current limit, and red for fault. The module also provides a “DC OK” relay contact (changeover) that signals when the output voltage is within ±10% of nominal, allowing integration with supervisory systems.

Installation and Wiring

Terminals are screw‑type, accepting up to 2.5 mm² wire. Input and output terminals are clearly marked (L, N, PE, +V, -V). The module includes a built‑in fuse on the input; replacement instructions are provided in the manual. It is recommended to install the unit in a well‑ventilated cabinet, observing minimum clearance distances.

Compatibility with Atlas Copco Systems

This power supply is certified to work with all Atlas Copco controllers that require a 24 VDC input, including PF series, TC series, and various interface modules. It provides sufficient current to power a single controller and its peripherals, or multiple small modules in a daisy‑chain configuration.

Certifications and Standards

The 8433 0005 10 complies with UL 508, CSA C22.2, and IEC 60950‑1 safety standards. It also meets EN 61000‑6‑2 (immunity) and EN 61000‑6‑4 (emission) for industrial environments. The unit carries CE and UKCA markings.

Applications

Typical applications include powering standalone tightening stations, retrofit kits, and test benches. It is also used in distributed control systems where a reliable DC source is needed for sensors and actuators. Its wide input range makes it suitable for installations with unstable mains supply.

Maintenance and Service Life

The power supply uses electrolytic capacitors rated for 100,000 hours at 40 °C, ensuring long service life. Routine maintenance involves checking for dust accumulation on the ventilation slots and ensuring proper airflow. The unit is not user‑repairable; faulty units should be replaced by authorised service personnel.

Advantages

By providing a stable, isolated 24 VDC, this module protects sensitive electronics from mains fluctuations and noise. Its high efficiency reduces heat generation, lowering cabinet cooling requirements. The comprehensive protection features minimise downtime caused by electrical faults.

Conclusion

The Atlas Copco 8433 0005 10 power supply module is a reliable and efficient choice for powering critical automation components. Its robust design, safety certifications, and seamless integration with the Atlas Copco ecosystem ensure dependable operation in the harshest industrial conditions.
