AC 2000

Product catalog summary

Application
The document describes a switch-mode power supply unit designed for industrial applications, providing secured DC power in combination with a parallel battery. It is suitable for various DC consumers, including constant voltage and current sources, and is applicable in rail vehicles, ships, and telecommunications systems.

Design and Features
The unit is compact, designed in 19" technology, and operates according to an IU characteristic line to DIN 41772 / DIN 41773. It is pre-wired and ready for installation, with front-accessible connections and controls. Key features include high efficiency, low weight, low mounting depth, high power density, low inrush current, sinusoidal input current, low voltage ripple, and resistance to sustained short circuits.

Operating Principle
The power supply transforms single-phase AC voltage to smoothed DC voltage, achieving a power factor of > 0.99. It uses transistors to generate a 100 kHz AC voltage, which is then rectified and filtered to reduce voltage ripple. Output voltage and current are controlled by pulse width modulation.

Parallel Operation: Unlimited number, load sharing approx. 10%

Monitoring and Indication
The unit includes mains-side and output-side monitoring systems with LED indications for various conditions such as over/under-voltage and over-temperature. External functions include a central fault signal and external sensor lead for output voltage.

Mechanical and Environmental Specifications
The unit is designed as a 19" module with ingress protection IP 20 and complies with EN 50178 for mechanical strength and vibration resistance. It operates within a temperature range of 0 °C to 45 °C and can be stored between -30 °C to 70 °C. It is suitable for installation up to 1000 m above sea level.

Standards and Approvals
The power supply complies with various standards, including EN 61000-6-4 for interference emission, EN 61000-6-2 for interference resistance, and EN 60950-1 for safe electrical disconnection. It holds CE approval and ISO 9001 certification.

Catalog excerpts

AC 2000 MODULAR SWITCH-MODE RECTIFIER DESIGNED FOR INDUSTRIAL APPLICATIONS Output Rating from a single rectifier: 65 A (at 24 Vdc) Application For all industrial applications. Provides secured DC power in combination with a parallel battery, for supply of all types of DC consumers including constant voltage and current sources as well as on-board power supplies for rail vehicles and ships as well as power supply to telecommunications systems. Compact in 19" technology The switch-mode power supply unit operates according to an IU characteristic line to DIN 41772 / DIN 41773. It is a pre-wired unit supplied ready for installation. The connections are accessible from the front panel. The controls and display elements are installed at the front of the unit. Due to its high effi ciency, it is designed as a compact 19" plug-in module of 4 height units. It is fully equipped for installation in sub-racks to DIN 41494. Operating principle The single phase mains AC voltage is transformed to smoothed DC voltage for sinusoidal current consumption. This allows it to achieve a power factor of > 0.99. From this, transistors generate an AC voltage of 100 kHz. With the assistance of transformers, the potential separation and the voltage adjustment take place at the secondary side. The high frequency AC voltage is then rectifi ed by means of rapid-acting diodes. An output fi lter is installed to reduce the voltage ripple. The output voltage and current are controlled by pulse width modulation of the transistor switch on the primary side. Key features » Compact design and low weight » Low mounting depth » High power density » Low inrush current » Sinusoidal input current » High efficiency » Low voltage ripple » Resistant to sustained short circuit » Excellent dynamic response POWER SOLUTIONS
