PM500 a new generation 500 W convection cooled DC/DC converters. It's a free standing unit that can be mounted on wall, chassis, DIN-rail. The units fits into 19"-rack mounting 2U and can be stacked with the optional panels as 2 pluggable units 2U or 5 units with 6U panel.
Inputs 110 and 220 Vd.c. with outputs 13.2 - 110 V. Very low noise input and output.  As an option 24 and 48 V output meet the EN55022 level B.
Wide input voltage ranges to meet requirement in railway or vehicles are available.

How can a standard DC/DC converter meet the Smoke and Fire standards?

The purpose of EN 45545 is that train coaches are designed in such a way that passengers have enough time to evacuate in case of emergency. EN 45545 regulates all fire safety aspects for railway vehicle and defines three requirement levels (hazard level), depending on the type and area of operations, whereas HL3 stands for the highest level. The so far national fire safety specifications for the railway industry were being supplemented by the new European Fire Safety Standard EN 45545.

The obvious solution is to put all electronics into fire enclosures, which however is not always possible. One key aspect for Polyamp’s product success is that we use a more expensive, but extremely solid aluminum case to protect their DC/DC converters. This ensures not only very good cooling, but also high mechanical stability, protection against dust and excellent EMC performance. Thanks to this product concept Polyamp’s engineers realized the fulfillment of EN 45545 within short time with only small modifications.

Additional information: The 30 to 500 W units fall in the category of “non listed product” < 100 g of EN 45545-2. The connector is less than 20 g and approved NFF16 101/102 and thus also meeting UNI CEI 1170, DIN5510 Class III, BS 6183.

Following film shows an demonstration, duration 57 seconds.

Polyamp have significantly updated its proven Multi Influence Sensor System UMISS©.
Significant Improvements is reduced size and weight and increased functionality such as:

• Increased frequency range for the Magnetic and Electric sensors; now up to 3kHz user selectable
• Enhanced Inclination sensor and a new Humidity sensor
• Sea cable can now be ruggedized copper cable Ethernet TCP/IP with extended range up to 1000 meters
• The UMISS© standard software has improved with Waterfall, FFT analysis and more

After the enhancement the updated UMISS sensor is called the UMISS© MKII. The UMISS© MKII is already in proven International use.
See the separate data sheet of the UMISS© MKII for more information.

What else do you wish from a labb power supply?

SM3300 has both one and three phase input, built in Ethernet interface with sequencer. You can adjust all parameters from the display and store the setting on a USB. In reverce you can set settings and sequences from a USB. They can off cause supply voltage and current that has both electrically and audibly low noise. 5 models and 4 with autoadjusted double voltage and current ranges.

In beginning of Mars 2012 the CVN77 set new record in Deperming. Polyamp feels that our system was an important factor to achieve this record.
Polyamp supplied mid 2008 a Degaussing system to the CVN77 carrier. It is the largest Degaussing system Polyamp has ever designed and delivered with 360 kW installed power. The 10 January 2009 it sailed out from the shipyard Newport News Shipbuilding, Virginia to start commisioning test.

Åtvidaberg March 17, 2010 - Polyamp AB was recognized for its quality and performance by Raytheon Integrated Defense Systems. Polyamp received the Five Star in the Supplier Excellence Award at a ceremony held on March 2, 2010.

Raytheon recognizes its suppliers based on three important factors: on-time delivery measures, sustained performance on quality and commitment to continuous process and quality improvement. The Five Star is the highest rank within the Supplier Excellence Award.
