You ask and we answer: Today the question is - How do you test the 4-20mA output of an infra-red device? Testing the 4-20mA output of your infra-red device is crucial to ensure accurate temperature measurements and reliable performance in your application. Here are our simple steps to check that everything is working correctly: 1. Make sure the infra-red device is correctly powered and connected to a 24V DC supply, which is standard for 4-20mA loops. 2. Set up a multimeter to measure current in milliamps (mA). Then, connect it in series with the 4-20mA loop. This involves disconnecting one wire from the loop circuit, attaching one lead of the multimeter to the wire, and the other lead to the terminal where the wire was disconnected. 3. Infra-red devices have a means of simulating different temperature readings. Adjust the settings to simulate a range of temperatures and observe the corresponding current readings on the multimeter. 4. The multimeter should display a current between 4mA (representing the lowest end of the temperature range) and 20mA (representing the highest end). Verify that the current changes linearly with temperature changes. 5. If the readings are not as expected, there may be a need to calibrate the device or check the connections for any faults. By following these steps, you can confirm that your infra-red device’s 4-20mA output is functioning properly, ensuring accurate temperature monitoring for your project.

Three phase variable transformer with motor and remote control. Output range up to 900Vac A big transformer company required us a test bench to supply different loads under test. The output is based on a motorized three phase 3x60A variable transformer. An output autotransformer provides 3 different output ranges, 0:100V, 0:500V and 0:900V. Required range is selected by remote contacts and operated by interlocked contactors. Output variation can be done throug the panel push buttons or by a remote control. Unit is provided by a panel lcd multimeter, protections and Emergency power off button.

Measurand created the Portable Diagnostic Unit (PDU) in order to offer clients a convenient and cost-effective means of verifying the patented cyclical installation of SAAV. This ensures that your ShapeArray is able to provide the most accurate deformation data possible. Acting as an interface, the PDU manages the communication and power between the ShapeArray and the computer. It is equipped with a high-quality DC to DC converter that boosts and regulates the voltage from the 10.80V Lithium-Ion battery to a constant 13.5V. The PDU also has the capability to increase the voltage to 16.5V, allowing for the use of longer communication cables. With a rapid charging battery, the PDU can fully charge in just 105 minutes. Its USB-C connectivity enables both communication and power to be supplied through a single input.

This is a smart breaker, presumably one part is a low cost mechanical breaker, then in series would be the smart relay for the Live as well as for PEN. Those 40A relay also not expensive part nowadays. Then there will be energy metrology circuits as well as PEN voltage measurement, they are also fairly standard low cost circuits. Adding J1772 circuits is also not expensive, just 1kHz PWM circuits. The main function would be connecting the relay when the Server or User said so AND the PEN is safe. Put this on the Consumer box and wire up the appropriate cable. Even adding HomePlug Green is not required bigger space too. If the spirit is efficiency, less should be cheaper. #efficiency #lowcostcharger  #chargereverywhere #micro_ocpp
