AC/DC converters.

The latest models in the PULS Power PIANO series have been introduced to the market. The PIANO-PIM family have been designed for use in the many industrial applications which only require a basic power supply so that customers do not have to pay for unnecessary control and communication facilities.

Marco van der Linden, UK Country Manager for PULS Power, comments, "Our PIANO range continues the PULS philosophy of offering our customers “more with less”. Our new PIANO-PIM range of power supplies are ideally suited for worldwide applications requiring a simple, basic, cost effective power supply with no compromise on quality. The compact size of the PIM36, PIM60 and PIM90 allows more flexibility in system design while the simple installation provides significant time and cost savings. PULS power supplies continue to set new records in their respective performance classes in the quality-critical functions such as efficiency, lifetime and size."

The PIANO-PIM series offer a cost effective, space-saving, efficient, reliable and durable DIN-Rail mounted AC/DC converters. The 100-240VAC wide range input, 24VDC output units are available in three versions: PIM36 (36W), PIM60 (60W) and PIM90 (90W). With these additions to the already very successful PIANO power supply range PULS now provides users with a complete, cost-oriented, product family with outputs from 30-480W. At ambient temperatures between -10°C and +55°C, the devices work at full power without derating. The PIM90 is also available as an NEC Class 2 version for the US market.

This range uses innovative technology to make savings in cost and space. The single PCB design uses a reduced number of high-quality components, lowering cost, simplifying manufacture and improving reliability. The PIM90 is currently the smallest 90W DIN-Rail power supply on the market. The compact design saves space on the DIN-Rail in the control cabinet and makes them ideally suited for decentralised use in cramped systems or spaces – e.g. building automation.

The high efficiency synchronous rectifier design based on MOSFET technology (90W PIANO achieving over 93.8% at full load and +40°C ambient temperature) reduces the need for system cooling and further increases reliability. With exceptionally low losses even in idle or standby mode at < 0.5W, the PIANO-PIM range particularly is useful for applications in building automation. In building safety systems power supplies often remain in standby mode for days or even weeks. Due to the very low no-load losses in the idle state, considerable energy costs can be saved over the long term.

The high efficiency and optimised thermal design allow polycarbonate housings to be used, reducing weight and providing a robust impact resistant enclosure. The use of a plastic housing means the small, low power PIANO power supplies can be operated without grounding, saving additional installation time and cabling costs.

The PIM60 and PIM90 power supplies are available with either screw terminals or time saving push-in terminals. PULS devices are optimally prepared for automated wiring processes. The PIANO-PIM range meet all international safety agency approvals and are CE marked.

Transducers enable true RMS measurement.

Knick have defined a completely new class of AC/DC transducers for true RMS values with the announcement of their series P 43000 TRMS AC/DC high voltage transducers. Input values range from 100 mA up to 5 A AC. They are output as standardized analog DC signals (0…20 mA, 4…20 mA, 0…10 V).

A rotary switch on the front facilitates comfortable, calibrated switching between up to 16 customized ranges. Traditional AC/DC transducers are very susceptible to errors due to their poor insulation and are only designed for pure sinewave measurement. The Knick P 43000 TRMS, however, has been developed to also accurately process distorted input signals. The highly accurate true RMS circuit converts signals with a crest factor of up to 5 in the frequency range of 40 Hz to 1000 Hz or 8 Hz to 400 Hz. The VariTrans P 43000 TRMS withstands working voltages up to 3600 V AC/DC and test voltages up to 15 kV. Protective separation of the input, output and power supply provide protection from electric shock up to 1800 V AC/DC according to EN 61140.

Knick's own TransShield technology facilitates an extremely compact, shielded design of the high-voltage transformers, allowing the VariTrans P 43000 TRMS to fit into a very compact, only 45 mm wide housing. Vacuum encapsulation provides maximum long-term protection against aggressive environmental influences, shock and vibration. In addition, VariTrans P 43000 TRMS transducers come with an integrated VariPower broad range power supply for supply voltages from 20...253 V AC/DC, which ensures maximum safety even in regions where auxiliary power is shaky.

Knick VariTrans P 43000 TRMS transducers come with a five-year warranty.
