The built-in diagnostic LEDs provide immediate status indication, enabling quick troubleshooting and maintenance.

Technical Specifications:

Input Characteristics: The power supply module accepts a wide input voltage range of 100 to 240V AC (+10%/ -15%) at 50/60Hz. The input current is 1.0A maximum at 100V AC and 0.5A maximum at 200V AC. The module features inrush current limitation of 40A maximum at 100V AC and 65A maximum at 200V AC. The input includes automatic range switching and requires a maximum power consumption of 50VA.

Output Performance: The module provides a stabilized 5V DC output with a rated current of 3.0A for the controller base unit and connected modules. The output voltage tolerance is within ±5% under all load conditions. The output ripple noise is maintained below 50mV peak-to-peak. The voltage regulation is ±1% for line variations and ±2% for load variations. The module offers a typical efficiency of 70% at full load.

Protection Features: Comprehensive protection includes overload protection with automatic recovery, overvoltage protection with latch-type operation, and thermal shutdown with automatic recovery. The output is short-circuit protected with current limiting and automatic recovery. The module incorporates input fuse protection and surge absorption circuitry.

Environmental Specifications: The operating temperature range is 0 to 55°C with derating above 40°C. The storage temperature range is -25 to 75°C. The relative humidity rating is 10% to 95% non-condensing. The module can operate at altitudes up to 2000 meters above sea level. The vibration resistance is 10 to 57Hz with 0.075mm amplitude and 57 to 150Hz with 1G acceleration. The shock resistance is 15G for 11ms duration in three axes.

Mechanical Characteristics: The module dimensions are 30mm x 130mm x 120mm (W x H x D) and it weighs approximately 300g. The module is designed for mounting in the NJ controller base unit using the built-in locking mechanism. All connections are made through the backplane interface with screw-type terminals for input power connection.

Safety and Compliance: The module meets UL 508 standards for industrial control equipment and is cULus listed. It complies with CE marking requirements for European markets. The design conforms to IEC 61131-2 standards for programmable controllers. The module meets EMI standards including EN 61000-6-4 for industrial environments and EN 61000-6-2 for immunity requirements. The isolation voltage is 2000V AC between input and output.

Diagnostic Indicators: The front panel features two LED indicators - a green POWER LED showing input power status and a red ERROR LED indicating abnormal conditions. The LEDs provide clear visual feedback for power status, overload conditions, and thermal protection activation.

Wiring Requirements: The input power connection requires 0.3 to 1.5mm² wire size with screw terminal clamping. The recommended tightening torque is 0.5 to 0.6N·m. The module includes removable terminal blocks for easy wiring and maintenance.

Application Notes: The NJ-PA3001 is designed to power the NJ controller base unit and all connected CPU, I/O, and special function modules. The power supply capacity supports maximum configuration of the NJ controller system. The module should be used with a properly rated circuit breaker or fuse on the input side for additional protection.

Reliability Data: The mean time between failures (MTBF) is 100,000 hours minimum at 25°C ambient temperature. The design life is 10 years minimum under normal operating conditions. The module uses high-quality components including aluminum electrolytic capacitors with extended lifetime ratings.
