ESX10-T Electronic Circuit Protectors with Hazardous Area approvals What Is a Power Supply Overview - Power supplies are essential links in supplying energy to control systems. They are the heart of every control cabinet. - Modern industrial automation applications require safe, efficient, packaged AC/DC power supplies to support DC voltage and current to the control systems used in factory automation and process control. - Power supplies are complimentary products to Weidmuller’s line-up of both active and passive products. Protecting 24VDC Circuits Circuit Breakers Fuses Electronic Circuit Protection Nothing Circuit Breaker 201 series thermo-magnetic circuit breaker trip curve…. May take 5-10 times the rated load to shut down or trip. Allows power supply to sag and stop supplying power to every circuit. Typically Over-Sized (80-125V). Susceptible to Nuisance tripping due to in-rush currents. Fuses Drastically affected by ambient temperature - Hot Temperatures – lower current needed to open. - Cold Temperatures – higher current needed to open. No ability to reset Typically requires 5X the current to open - Switch mode power supplies cannot provide sufficient current. - Voltage level will drop off before the fuse opens. Figure 3: Characteristic output curve of typical switch mode power supply Electronic Circuit Protection Will open current path before voltage sag Isolation of circuit failures Control Cabinet not affected by one failure Status and Signal output is available Visual Indication of failures Ability for remote reset Orientation doesn’t matter ESX-10T Trip Curve Our Solution ESX10-T Series Protectors Protects 12 VDC and 24VDC Power Applications Electronic Circuit Breaker - Remote Reset - Remote ON/OFF - N/O or N/C Manufactured by ETA Currently no Direct Competition Solid State Overcurrent Protector Active Current Limitation (1.3 to 1.8) Selective Load Protection Markets/Applications Markets/Verticals - Oil & gas Industry - Petro-Chemical Industry - Pharmaceutical - Water and Wastewater - Automation Systems • Machine Tool & Packaging Machines Applications - Hazardous Location - Remote Reset Signal - Remote ON/OFF Control Signal - Current Limitation (1.3 to 1.8 times Amps.) Application Benefits (ESX10-T Series) Increased System Uptime Faster Trouble-Shooting and Problem Solving One design for North America - UL 1604 Listed (Class 1 Division 2) - CSA Approvals are in process. Improved Design and Installation - Reduction of “Real Estate” - Decreased commissioning time Not Affected by temperature Minimizes “Nuisance-Tripping” One Trip Curve for all Breakers The Competition Competition (ESX10-T Series) Siemens Sitop Select (Fuse) - Risk of incorrect current rating adjustment Shuts down when voltage drops below 18V Mechanical reset necessary after shut down Have to reset all four channels at once Complex handling and can loose fuses Not easy to identify problems Risk of destruction if fuse is re-inserted without failure remedy. - Only Available as a 4-way module Competition (ESX10-T Series) Murrelektronik MICO 4.x (Fuse) - No physical Isolation with disconnection No real current limitation Difficult to wire on DIN rail Remote reset is possible and wired separate Functions only compatible with MURR Systems Only a 3-way unit with ratings up to 10A Extended voltage interruptions lead to shut down Adjustable current ratings leads to disconnect Trip behavior depends on cables used Key Questions How do you currently power active devices and electronics in your automation control panels? Do you use switch mode 24VDC power supplies for equipment in your panels and machines? Are you protecting your critical loads, such as PLCs and Ethernet switches, from, power supply failures? If so, how? Are you satisfied with the time it takes to identify and troubleshoot power-related failures in your controls panels? Are you satisfied with the reliability of your DC power sources?
