Power Supply

• Longer lifetime for connected loads
• Less heat dissipation
• More compact construction
• More functions
• Easier installation

Its essential characteristics are:

• 24 V/2.5 A, 5 A, 10 A, 20 A and 40 A for standard applications
• 24 V/10 A wall-mounted for high shock and vibration requirements
• Capable of providing extra power (150 %) for brief operational overloads
• Can be permanently overloaded with 120 % (provided ambient temperature is less than 45 °C)
• No lateral installation clearances required
• Output voltages are adjustable up to 28 V
• PSU300S: With signaling contact „24 V DC OK“
• Comprehensive certification, e.g. GL and ATEX
• Expandable with DC UPS, and extension modules

• For demanding applications from 5 to 40
• DC/DC converter 24 V/20 A for drive and battery networks
• 48 V/10 A and 20 A enable small cable cross-sections
• Compact metal enclosure
• No lateral installation clearances required
• Wide-range input
• Extra power of 150 % for brief operational overloads
• Power boost of 300 % for tripping protective devices
• Selectable short-circuit response
• A soft characteristic can be selected for parallel connection
• High efficiency
• Operating status on 3 LEDs
• Expandable with SITOP add-on modules and DC UPS

• SITOP modular fulfills the highest functionality requirements, e.g. for use in complex plants and machines. The wide-range input allows a connection to almost any electrical power system worldwide and ensures a high degree of safety even if there are large voltage fluctuations. The power boost provides up to three times the rated current for brief periods.
• In the event of an overload, you have two options: Constant current with automatic restart or latching shutdown. The innovated power supplies SITOP PSU100M 20 A with 1- phase connection, the SITOP PSU300M 20 and 40 A 3-phase, and the SITOP PSU400M 20 A with a second DC input have even more to offer. Due to their slim design, they are among the most compact units in their performance class. The innovations include the integrated signaling contact for "24 V OK", the extended input range, the high efficiency and 1.5 times the rated current for up to 5 seconds.

• Efficient and cost-effective: The high efficiency of up to 90% of the power supplies guarantees considerably less power consumption and distinctly lowers the heat dissipation. This reducing the need of forced cooling. It further results in lower current operating costs without loss in power. The light and compact power supplies eliminate the need of huge panels which further brings down the panel costs.
• Extend the lifetime of your equipment: The constant stable 24V output voltage protects modules against over voltage and under voltage in the extended allowable range of variations of the input voltage. This not only improves the operating safety but also ensures a longer lifetime of the modules.
• Build in safety with built-in safety: It is owing to the integrated electronic short-circuit protection that has done away with the need of additional fuses in the 24V circuit. A substantial output buffering time ensures a minimum power for some time immediately after a mains power failure. This makes it highly suitable for use with programmable controllers. The power supplies are available in the technical specifications.

• Sipower: When it comes to design, reliability, protection and cost-effectiveness, these indigenously developed and manufactured switched mode power supplies stand ahead of the best in the world. With a unique price by performance ratio, Sipower power supplies fit in perfectly for lower power application of single phase 24V/2A and 24V/5A. Sipower is highly suitable for the Indian power/mains conditions, owing to the various protection and safety functions and ability to withstand tough environmental conditions. The economy is ensured by saving upfront cost and running costs due to low price and high efficiency.
