Camtec fabricates Programmable DIN-Rail Power Supplies for the Test Automation, similar to a Laboratory Power Supply.
A Camtec Switch Mode Power Supply SMPS is designed for pro-applications like infrastructure, railway, traffic control or military use. Camtec’s products provide outstanding data. Camtec power products achieve CE, RoHS and REACH, as well as the new European (Energy-Using Products) EuP Eco-Design Directive.
Their portfolio includes Unbreakable Power Supplies, DC-UPS, Battery Chargers and Charging Rectifiers for the modular DC-UPS, up to 60KW.
Camtec also provides Redundant-Modules, Inrush Current Limiters and Electronic DC-MosFET Relays for the Automation Powertrain
Since 1995 Camtec has been a leading German supplier of demanding power supply systems. The product portfolio includes one-phase and three-phase embedded power, DIN rail power supply, enclosed box power supply, base plate cooled power, FET-based DC power switches, programmable power supply and a family of very exact electronic AC inrush current limiters for capacitive loads.
Custom power supply systems
Camtec is a specialist in creating demanding power supply systems, particularly for natural cooled AC/DC power supplies.
Camtec’s products are used in various outdoor applications, such as traffic control systems, infrastructure and high-power LED lighting, railway, armed forces and automotive and in high-power DC-UPS chargers up to 100kW.
Camtec Power Supplies is no mass manufacturer. Camtec’s profession is the demanding application of high-end integrated systems.
Camtec’s standard products already provide a smooth C/V characteristic to start very complex loads such as LED lighting, DC/DC-converters and serious DC motor drives. Camtec’s DIN rail power supplies are designed for base plate cooling on a hard mount. All switch mode power supplies are designed for natural cooling and with a standard ambient temperature between -20°C to 70°C.
The mechanical design of Camtec’s products is extremely robust and is made for long-term use. Camtec’s design standard is 17-18 years and uninterrupted service at 40°C. Camtec uses only high-end brand electronic parts from the best manufacturers in the world.
Camtec’s quality management integrates an ISO9001:2008 certification and a UL-controlled production.
Electronic inrush current limiters
The Camtec ESB-series is the second generation of cost-effective electronic AC inrush current limiters. The limiters ESB101, ESB201 and ESB00351 are made for one-phase 115/230Vac 16-30A networks. The ESB00163 and ESB00323 are designed for three-phase 200/400/500Vac 16-32A networks.
The line frequency range varies from 16.5Hz – 440Hz. The ESB-limiter is located between the line-switcher/contactor and the load. The ESB-models are designed for inductive and capacitive loads.
The main use is to protect the installed MCB from tripping. It protects power relays and contactors from burned contacts while switching various switch mode power supplies. The ESB is used to protect AC-UPS converters to operate into the current limiting mode and undesired overpower shutdown.
When switching-on the system, the inrush current of the installed load will be limited for the defined time Ton. Independent from the previous inrush level, the current limiting is always strict to the selected peak level. After Ton elapses the current limiting circuit of the ESB will be bypassed. The electrical network can be stressed with current loads as normal. If an AC dump overshoots the defined time Toff, it will be detected by the ESB. As soon as the AC recovers the inrush will be limited, again. The limiting occurs in each phase independently. The ESB-family provides an internal temperature control.
In case of a failure the device shuts down to safely prevent overheating or burning. The standard ambient temperature varies from -40°C up to 70°C without derating. Electrical parts are fixed against shock and vibration. The operation altitude is up to 13,123ft (4000m) above sea level.
AC/DC switch mode power supplies on DIN-rail
Camtec is known for exceptional lifetime and high-performance SMPS on DIN Rail. Customers in 50 countries worldwide rely on Camtec’s products in demanding applications. The product range of the HSW, HPW, HPV and HSE families provide 10W to 1,500W output power. The voltage ranges from 5Vdc to 400Vdc. 95% of the SMPS are designed with natural cooling -20°C to 70°C. The HSEUreg- and the HSEUireg-series is an interface programmable DIN rail power supply family from 0 to 400Vdc. Its operation quality easily reaches the level of demanding laboratory power supplies.
The Camtec DIN rail SMPS are designed for critical loads like DC-drives, DC/DC-converters, piezo drives, LED-drivers and battery charging. The products combine high-density packaging and an exceptional lifetime performance. 3kV or 4.2kV electrical isolation is a standard. Fixed parts to resist vibration and shock, e.g. optional coating for each product, are standard.
The power supply is used in a large variety of applications, including traffic control systems, railway, defence, offshore, plant building, test benches, science, infrastructure and cities.
Battery chargers and DC-UPS
Camtec offers various rectifiers ranging between 480W DIN Rail to 3kW embedded power modules. Camtec can deliver a complete custom-made DC-UPS system from a simple KISS-UPS to a complex charger for railway or IT systems. A setup of a maximum of 100kW controlled DC-charger is possible. All chargers perform fixed parts and optional coating as standard.
