If a transmitter is tested without a load attached to its output terminals such as an antenna or a dummy load, the power will be reflected back into the transmitter, often overheating and damaging it. Veterinarian-grade mineral oil, an inexpensive form of mineral oil, is frequently used by amateur radio operators as coolant in RF dummy loads. Bell boxes come in all shapes and sizes and various levels of volume normally between 109db and 115db.

Our goal is to provide one stop place for electricians and electrical contractors, but we are happy to help other clients too. This is a Dummy Dimmer switch, which has only a On/Off Push function so it is made to look like a dimmer switch on your existing dimmer plate.

Further developed electronic loads supply several operating modes, in most cases constant current, voltage, power and resistance.In case where only mechanical characteristics are required, dummy components can be used instead of live functioning components.

The Electrical Counter is constantly adding to their innovative product ranges using industry leading brands and manufacturers to supply a wide variety. The dummy load ordinarily should be a pure resistance; the amount of resistance should be the same as the impedance of the antenna or transmission line that is used with the transmitter (usually 50 Ω or 75 Ω). The technical storage or access is strictly necessary for the legitimate purpose of enabling the use of a specific service explicitly requested by the subscriber or user, or for the sole purpose of carrying out the transmission of a communication over an electronic communications network. Analysis and implementation of an electronic load controller for a self-excited induction generator". Kits are available in a single pack, for employee hand soldering training, or packaged for production equipment evaluation.The equipment and power spectrum of such electronic loads begins with simplest circuits consisting in general of a potentiometer for current setting and a transistor circuit for power transforming. With the test dummy PAS400-HPIA-1 you get a test dummy in a plastic housing for HV, PE, ISO and AI tests. When testing audio amplifiers, it is common to replace the loudspeaker with a dummy load, so that the amplifier's handling of large power levels can be tested without actually producing intense sound. When loading a current source with a fixed resistor one can set one determined load current by the connected load resistor.

The precise ISO calibration resistor ST3030 can be used for voltages up to 20 kVDC and for insulation tests with 1 GOhm and leakage current tests with 50 kOhm. AC loads are used to test transformers, uninterruptible power supplies (UPS) or onboard power supplies. It is substituted for the antenna while one adjusts the transmitter, so that no radio waves are radiated so that the transmitter does not interfere with other radio transmitters during the adjustments. The Engineer from AG ELECTRICAL designed GB/T DC Dummy socket according to the real usage scenario in China.

Also, if a transmitter is adjusted without a load, it will operate differently as compared with a load, and the adjustments may be incorrect. Way Push-On/Off Switch Module (Dummy Dimmer, push on/off only ) 6ACan be used to replace dimmer modules in existing faceplates1- or 2-way switchingidentical in appearance to dimmer switch without dimming functionPush-on/off function onlyBritish made Technical Information Dimensions: 50x26x42mm Operating Voltage: 230v 50Hz Maximum Load Rating: LED: 6A Maximum Current Rating: 6A Terminal (Live) Diameter: 3. Designed to be used on-grid faceplates where you require the outlook of a dimmer but the function of just a switch.
