Based in Sweden and specialising in DC power conversion, Polyamp is a developer and manufacturer of both AC/DC power supplies and DC/DC Converters.

With over 50 years’ experience in development and production of DC/DC converters, Polyamp can provide a wide variety of DC/DC converter combinations to high reliability standards. From 50W DIN Rail converters to 1kW rack mount options, the Polyamp range offers numerous options to cover many requirements. What’s more, many of these units allow current sharing allowing users scalability in their existing systems. If you have a requirement for DC/DC converters, contact CP Power (UK Distibutor for Polyamp) with details of your requirement so one of our engineers can help.

Alongside their DC/DC offering are Polyamp’s power supplies. Specialising in high quality rack mounted solutions, customers that require a cassette-style mounting system with H15 connectors can use the PSC range of products. Alternatively, multiple mounting options are available for each of the ranges allowing a traditionally rack mounted unit to be mounted on DIN Rail or chassis mounted making them versatile to your requirements.
 

One of Polyamp's smaller units, the PM range of DC/DC Converters offers solutions from 50W, up to 500W outputs. Whilst being the smaller units, they offer a variety of options for use:

• Flexible Mounting Options: Compatible with wall, DIN-rail and 19" Rack Mounting, with numerous accessories for mounting options.
• Wide Input Voltage Choice: With converters supporting input ranges from 10 to 300 VDC, there are options for various systems. Meeting industry standards like EN 50155 and IEC 60571, they can easily be used for railway and industrial applications.
• Multiple Output Voltage Options: With Single and dual output voltage options, industrial solutions can be offered when 2 outputs are required from a DC input.

PSC Range

The PSC is a wide range of units, ranging from the PSC80 that eventually powers up to the PSC600. Primarily designed as a Euro-Cassette style of mounting, some of the advantages are:

• Flexible Mechanical Configurations: Available in three designs—Euro-format with DIN connectors, screw/stud connections, or plugin options for Euro sub-racks. Additional heat sinks and military-grade circular connectors can enhance power handling, temperature performance, or ingress protection (up to IP65).

• High EMC Compliance: Designed for demanding electromagnetic environments, meeting EN IEC 61000 and EN 50121-3-2 standards, with immunity to high levels of interference, including ±4 kV surges and up to 20 V/m radiated immunity.

• Versatile Input and Output Ranges: Supports wide input voltages from 10 to 550 VDC, optimized for nominal battery voltages (24 to 440 V). Offers single outputs ranging from 5 to 125 VDC, with power capacities up to 240 W, ensuring compatibility with various industrial, railway, and military applications.

PU Range

The PU Range of DC/DC Converters are Polyamp's range of rack mounted DC/DC Converters that have a high amount of features. Available from 300W up to 1kW per unit, they can be put in parallel for larger systems and solutions. The key advantages of these units are:

• Advanced Load Sharing and Redundancy: Features current-sharing capabilities for parallel operation of up to 10 units, ensuring balanced loads and scalability. Built-in series diodes provide output redundancy when used in parallel configurations.

• Comprehensive Safety and Protection Features: Includes reverse input voltage protection, overvoltage protection (limits to 15% above nominal), and over/under voltage alarms with relay outputs. Meets EN IEC 61000-4-5 level 4 standards for surge protection, ensuring reliability in harsh environments.

• Durable and Efficient Design: Fully encapsulated for IP20 protection, conformally coated for up to 98% non-condensing humidity, and highly efficient (>88%). Operates within a temperature range of -25°C to +55°C, with options extending to -40°C and +70°C for demanding applications.

• User-Centric Functionality and Flexible Mounting Options: Front panel controls allow easy adjustment and monitoring of output voltage, with status LEDs and external voltage sensing to compensate for load drops. The units can be mounted in 19" racks or with brackets, with additional options for heat sinks or military-grade connectors offering ingress protection up to IP65.

PC Range

Polyamp's range of large output, rack mounted DC/DC Converters are ideal for simple 19" rack mounting, scalable systems and simple features for integrators. Key features include:?

• Flexible Power Delivery: Handles input voltages from 20 to 300 VDC, with single output options ranging from 24 to 48 VDC. Offers up to 1000 W with convection cooling and up to 2000 W with fan cooling.

• Robust Protection Features: Includes inrush current limiting, reverse input voltage protection, and overvoltage protection (OVP) with a backup regulation circuit.

• Advanced Load Balancing and Redundancy: Supports current sharing for parallel operation of up to 10 units, with optional series diode outputs for redundancy, making the PC2000 ideal for scalable and critical systems.

• User-Friendly Monitoring and Controls: Front-panel adjustable output voltage, external voltage sensing (compensating up to 5% voltage drops), and alarm circuits with relay outputs provide easy monitoring and precise control over performance.

• Durable Design for Harsh Environments: With high efficiency (>89%), operating temperatures of -25°C to +55°C, and optional conformal coating, these converters are built for demanding conditions, including high humidity and environments prone to condensation.
