The DTP-37A is an electronic potentiometer that has a 220-volt power supply and a size of 37x72 mm. You can find the panel cutting dimensions in the product image.

This device can provide digital and analog output, specifically: 010V, 020mA, or 4~20mA. It is a digital potentiometer that is suitable for various applications where precise voltage or current control is required.

• The analog output value (010V, 020mA, or 4~20mA) can be adjusted from the front panel.
• Soft start or stop can be adjusted.
• The decimal point location can be set.
• The SET value limiting range can be set.
• The LED display has custom icons (12mm 4 digits).
• The front panel is IP65 protected against dust and water.
• It can be mounted with a fixed terminal.
• It can be fixed on the panel cutout with a clip-in mechanism.

• The device can store the last set value in its memory in case of power loss.

• There is no additional digital input for increasing or decreasing the speed.

Please note that this device cannot be used as a regulated power supply!!! Its production purpose is mainly to provide a reference source for motor drivers or servo systems. The current it can supply is at the mA level.

The device is easy to use and can increase or decrease the output analog value (DC 0-10V or 4-20mA) through digital buttons. If desired, the output voltage value can be proportionally adjusted to the machine's condition, either one-to-one or based on preference.

• 9 speed control devices (parallel/serial) can be connected to its output. You can find connection examples in the product image.

++ The DTP electronic potentiometer and analog control device are designed for industrial machine environments. It has galvanic isolation that allows it to operate next to potential noise-generating products like power supplies, frequency inverters, and servo drivers on the same panel.

Attention please: This device cannot be used as an adjustable power supply. Its production purpose is solely to adjust the reference of speed control devices. Do not connect any other receiver or load to its output.

Editor's note: Dear friends, this device is produced as a replacement for the REP series digital potentiometers. The features of the old version have been improved, and the entire casing type has been changed. In addition, the new microprocessor model has increased the resolution even more. With this series, the most common complaints we received, such as the buttons being too hard and the casing breaking, have been resolved. It is a very good model for its price. (Personal opinion)
