NK DS3-SDT-12U - DC Current Sensor, DS3 Series

 

• DS3 series
• DC current sensor
• Setpoint range = 2-20, 10-50 and 20-100 A, jumper-selectable
• Output type = SPDT Relay (Form C)
• Power supply = +12 VAC/DC

DS3 Series Current Sensing Switches combine a Hall effect sensor, signal conditioner, and a limit alarm into a single package. The DS3 Series offers three jumper-selected current input ranges and frequency response from DC to 400 Hz. Available in a solid-core case with choice of relay or a universal solid-state output.

Failure Detection

 

Current Sensing Switch Applications

 

Welders and Platers

• Instant indication of equipment status.

Large Drive Motors

• Provides enhanced field loss protection.

Power Supplies

• Signals overcurrent before equipment fails.

Machine Operation

• Instant status of motors, lamps and other loads.

Telecom Sites

• Monitors battery output.

Current Sensing Switch Features

 

Compact, One-piece Design

• Fits in easily amongst motor starters and power supplies in crowded control panels.

Input Isolation

• Safer than shunt/relay combinations.

Output Installation

• Isolated output greatly simplifies wiring.

Pluggable Terminals

• Speed installation.

Tough

• Designed to handle a wide range of temperatures found in industrial environments.

Adaptive Hysteresis

• Hysteresis is 5% of setpoint, allowing closer control than fixed hysteresis switches.

Built-in Mounting Feet

• Simple, two-screw installation allows for secure mounting.

UL/cUL and CE Approved

• Accepted worldwide.
