Dart - Dp4 And Asp Digital Speed Pots
DP4 Digital Speed Pot:
Digital display speedpot for AC or DC drives
Microcomputer based, the DP4 replaces conventional 3-wire analog speed potentiometer. Displays percent of motor full speed. Faceplate gasket kit. Universal power supply – one model for both 120VAC and 240 VAC input.
The DP4 now offers a configurable input to lock out set point changes via the front panel. This can add an important level of control for safety or system performance reasons.
A microprocessor based digital speed potentiometer that can directly replace a conventional 3-wire analog speedpot or motorized speedpot for most AC and DC drives. The desired set speed is entered into the large 1/2 inch LED display through the convenient front-panel interface…and display units are now programmable for virtually any unit of measure. The attractive panel mount unit is easy to install in industry standard 1/8 DIN cut-out dimensions. The electrically isolated common signal permits direct wiring from the unit terminal block to the drive’s potentiometer terminal points. The DP4 offers the same enhanced display options and capabilities featured in our other digital control products, as well as the Universal Power Supply and rugged screw type terminal strip.
1. Digitally set rates and speeds in engineering units
2. Provides a repeatable output
3. Eliminate operator inconsistency
4. NEMA 4 front panal
5. Wires right into the pot circuit of any drive.
ASP10 SMART Speed Pot:
SMART (Digital closed loop) speed pot for AC/DC drives under steady loads
Standard features include; 1/2″ LED display, master or follower mode, field programmable for rate or time, decimal point. Maximum input: 50,000 pulses per minute. Faceplate gasket kit. Universal power supply – one model for both 120VAC and 240VAC input.
The Accu-Set is a compact, economical control that can be used with conventional AC, DC, or Brushless DC adjustable speed drive systems to provide an LED display of set speeds and precise, digital closed loop motor speed control. An on-board microprocessor with non-volatile memory coupled with sophisticated internal software makes Dart’s Accu-Set the ultimate in accuracy and control. Target speeds are displayed directly in RPM, FPM, GPM, process time, or any other engineering unit of measure. Friendly front-panel field programming permits customizing the Accu-Set to the exact specifications for each application; maximum and minimum set speed, decimal points or colon, operating mode (master or follower), and the constant which takes into account motor gear ratios. The Accu-Set is simple to operate… just set the desired RPM, rate, or time in the large 1/2″ LED display by depressing the “up-down” pushbuttons, one digit at a time or fast sweep. The Accu-Set settings are exact and repeatable. It will precisely control speed to a remarkable ±1/2 RPM of set speed, long term. The panel mount unit is easy to install in the industry standard cutout dimensions of 1/8 DIN. All wiring connects directly to a rugged screw type terminal strip through the easy access rear panel.
1. Similar to the DP4, but adds digital speed feedback
2. Regulates the speed, ratio, process time, or even processes like pressure.
3. No drift... speed set equals actual speed
4. Repeatable
5. Multiple versions from simple feedback loop to full PID and communications
