What is it?----------------------------------------------------->

By using electromagnetic relays and resistors, we create high-precision adjustable resistors that can be controlled by a program.

These resistors have excellent repeatability, high accuracy, high power, high bandwidth, low temperature drift, and physical characteristics closest to those of fixed value resistors. These programmable resistors can be programmed to simulate or calibrate sensors such as RTDs.

About the draft prototype(fast delivery required):

• Modification based on RM550
• 4-15Ohm output
• 10mOhm step
• Full range rated at 24V (150W@4Ohm, 40W@15Ohm).
• ± (0.02% + 1 step) combined accuracy
• Temperature drift <300ppm
• Dimensions: 15x15x10cm
• The draft functional prototype is delivered in 5 days.

Why did you make it?----------------------------------------------------->

We currently have a series of programmable resistors, such as the QR10 resistor box and the RM55 resistor module, however it is far from being sufficient to meet the diversity of user needs. Therefore, we have launched the flexible customization service.

What makes it special?---------------------------------------------------->

• Extremely competitive price and first-class performance
• Fast delivery time

Capabilities:

• 0 (infinitely close) to 1.2MOhm Up to ±0.01% accuracy, up to better than 1mOhm steps
• 5-25ppm temperature drift, customized foil resistors also available
• 0.1-100W+ power ratings (as long as dimensions is not limited)
