June 2022: Dart Controls has announced that their popular 125D series will be discontinued. The replacement is the 150 series which has many additional features!
- Existing customers can continue to order the 125D through Q1 of 2023
- Starting in Q1 of 2023 everyone will be asked to make the switch to the 150 series (information below)
- January 1st, 2024 the 125D series will no longer be available
The Dart Controls 150 series is a better control that offers more features and higher performance:
- Drop-in replacement - same size, mounting method and mounting hole dimensions
- Accel/Decel adjustment was an option (-2A) on the 125D, it is a standard feature on the 150 series
- True dual voltage - the 150 series allows for 90VDC output from BOTH 115VAC and 230VAC supply
- Fusing option - 1 or 2 fuse holders may be added and mounted to the 150 series
- Choice of wire termination - 1/4" male QC terminals are standard, euro style terminal strip optional
About the 125D series:
The 125 series is a compact, cost effective and reliable SCR drive. SCR drives convert single phase line voltage (120/240VAC) into full-wave rectified DC for use with both DC permanent magent and shunt or field wound DC motors. Designed and built in the USA!
Installation and field adjustments are facilitated using a barrier type terminal strip and large, easily adjusted trimpots. Adjustable horsepower range: 120 VAC; 1/50–1/8 and 1/8–1/2; 240 VAC; 1/25–1/4 and 1/4–1. The 125D-C model operates on a low input voltage of 24/36 VAC with an output of 150mA–5.5 ADC.
Standard features include an inhibit circuit for star t-stop operation and 1% speed regulation over a 50:1 speed range. Dual voltage 120/240 VAC or 24/36 VAC models are available.
Long life and quality are assured by 100% full load testing. The 125 Series is ideal for applications such as: office machinery, conveyors, of ice packaging equipment, printers, process equipment, centrifuges, and exercise equipment.
- SCR drives control motor speed by adjusting the voltage output of the motor. SCR drives are the workhouse of the variable speed DC motor industry!
