Arroyo Instruments LLC

We offer both benchtop and OEM power supplies in a wide range of power levels, in both single channel, combo, and multi-channel configurations. If our standard products don’t meet your needs, we can often customize our solutions so that they do.

Our diode drivers offer high stability and low noise performance, suitable for both laboratory and high performance manufacturing applications. Output current ranges from 100mA to 100A, and some models include microsecond pulse (QCW) operation, with integrated pulse generator and pulse widths as narrow as 100 microseconds.



Our temperature controllers feature 0.004°C stability and output powers from 28W to up to 960 Watts! All of our controllers feature an integrated user adjustable power supply for an external fan, some have 4-wire measurement mode for RTD sensors, digital I/O, multiple sensor inputs.

We also offer multi-channel controllers for high-density test and manufacturing applications. Based on the same proven technology as our benchtop products, our MultiSource controllers are rack-mountable, high-performance solutions in both low and high-power configurations.

Our benchtop instruments feature a bright VFD display with an easy to use interface, while our OEM models offer a compact, displayless enclosure for embedded or low cost applications. All instruments include a USB computer interface, and many also include RS-232.
