Atlas SCR Thyristor and Triac Analyser
SCR100
Thyristors and Triacs need special test conditions to analyse effectively - that's where the new Atlas SCR comes in. The SCR100 can apply gate test currents from 100µA up to 90mA (with test load currents of up to 100mA) so it's not limited to sensitive parts.It will automatically identify the type of part (Thyristor or Triac), identify all three leads and also categorise the gate sensitivity. This new version takes a standard Alkaline AAA battery.

SCR Controlled DC power Supplies
Variable DC power supplies are AC to DC power supplies with a variable DC output. The output can be varied with an SCR controller. The AC input power can be single-phase or three phases. With single-phase AC input, the DC output ripple is very high (50%). With three-phase AC input, the DC output ripple is low (5%). This would be a key benefit for selecting three-phase AC input instead of a single phase.

AdBlue & Urea Refractometer
RHA-503ABATC
Fuzhou Zhongtuo Optoelectronic Co.,Ltd
The AdBlue refractometer RHA-503ABATC is a new hand held refractometer developed to address the growing need to check the urea concentration in AdBlue.Escalating urea prices have driven the cost of operating an SCR higher than ever before. Regretfully this has led to a new wave of problems where supplies of diluted AdBlue have found their way in to the market.Often rebranded ‘Automotive urea solution’ to eliminate the risk of prosecution by trading standards (as a mix of less than 31.8% urea cannot be labelled AdBlue). Victims of this weaker concentration may not be able to seek compensation under the Trades Description Act.

Calibration & Demag.
Model 8515-D
The Model 8515-D is a medium-energy, high voltage, and capacitor discharge type ringing demagnetizer capable of desaturating Ceramic and Rare Earth magnetic materials. The Model 8515-D is easily adapted to a wide range of production and laboratory demagnetizing requirements. A modern solid-state electronic control circuit, coupled with a rugged, heavy-duty discharge SCR and fixture, make this demagnetizer a highly reliable, low maintenance unit. The electronic voltage control circuit prevents the Model 8515-D from being discharged before the preset energy level has been reached, avoiding incomplete magnet desaturation. An easy to read front panel meter monitors the capacitor voltage. The energy storage level can be easily changed in the field. Integral electrical interlock and fail-safe circuitry provide a high degree of operator safety.
