DGL Tech has particular expertise in the following product categories. We generally get the best results by working closely with your engineers, with a shared goal of designing in parts that offer outstanding value. How do we define outstanding value?

Outstanding pricing. Outstanding features. Outstanding reliability. Choose any three!


Passive device that temporarily stores energy. Many specialized variations for industrial and automation applications. Approvals include UL ratings and P2 safety protection.

  • Electrolytic
  • Film
  • High Voltage
  • Motor Run
  • Power Factor Correction

Circuit Protection

There are few things more important than preventing overcurrent, overvoltage, and overtemperature faults that have the potential to damage your products and equipment. Circuit protection devices protect against surges, shorts, incorrectly wired power and environmental conditions

  • Breakers
  • Single Use Fuses
  • Resettable Fuses
  • Thermal Fuses


Make and break large electrical loads for automation equipment (heating, ventilating, pumps, motors, lighting). Accurate specification is critical to reliable operation. IEC ratings are application-based (lightweight contactors aligned to specific applications). NEMA ratings are general purpose based on horsepower and voltage (heavy duty contactors with large safety factors).

  • Definite Purpose
  • Magnetic
  • Mechanically Interlocked
  • Reversing /Non-Reversing


Disconnect power in distribution networks, mains, motors, and cabinets and enclosures. Options include dead-front construction, lockable mechanisms, interlocks, and more.

  • Door Interlock
  • Enclosure Disconnects
  • Finger Proof
  • Non-Fused
  • Open-Fused
  • Transfer Switch


Deliver key information through visual indicators. Options include numeric, alphanumeric, and full graphic displays.

  • Dot Matrix
  • Graphic
  • LCD
  • LED
  • Seven-Segment


Electrical enclosures house and protect electrical and electronic equipment. Protect users from equipment and equipment from the environment. Mount circuit breakers, switches, displays, lamps, wire ducting, etc.

  • Explosion Proof
  • Fiberglass
  • Modular
  • Temperature Controlled


Advanced technology means smaller, more efficient, and higher CFM products. Axial fans are appropriate for low backpressure systems and where noise is a particular concern. Blowers provide concentrated flow and operate well with high system impedance (large pressure drops between air inlet and exhaust). Design considerations include heat sources, an effective cooling path, noise limits, system impedance and thermal analysis.

  • Axial Fans
  • Ball Bearing Fans
  • Blowers
  • Centrifugal
  • Crossflow Blowers
  • Filters (NEMA 12)


Suppress conducted or radiated interference on signal and power lines. Used for emissions (suppress interference generated by your device) and susceptibility (prevent outside interference from reaching your device). Sometimes required to maintain compliance with FCC, CE, and VDE regulations.

  • Blocking Filters
  • Chokes
  • EMI
  • Entry Modules
  • Ferrites
  • RFI


Rapidly improving technologies provide great options for significantly more efficient lamps — that means less energy and longer life. On the other hand, a lack of standards makes for limited choices for interoperable high-tech lamps and controllers.

  • Displays
  • Incandescents
  • Indicator Lights
  • LEDs/Cluster LEDs
  • Pilot Lights

Motors and Drives

Couple quality motors with variable frequency drives. Variable frequency drives are excellent motor controllers as they ramp motors up and down with adjustable frequency and voltage characteristics (thus extending motor life).

  • AC Drive
  • DC Drive
  • Motors
  • Variable Frequency Drives

Motor Protection

Includes manual motor starters and overload relays. Manual motor starters are compact, eliminate fusing, and are fast reacting (milliseconds). Protect against short circuits, overloads, overtemperature, phase failures and locked rotors.

  • DIN Rail
  • Electronic
  • Fuseless Protection
  • Manual Motor Starters
  • Motor Disconnects
  • Overload Relays
  • Thermal

Power Supplies

Transform line voltage (AC) to low voltage (DC). Key characteristics include efficiency, output voltage, output current, peak power, ambient temperature rating, MTBF, and approvals. Considerable care is required to assure long-term reliability when specifying switching power supplies.

  • DIN Rail
  • Single-Phase
  • Switching
  • Three-Phase


Open and close circuits electromechanically or electronically. Switch current in control circuits. Typical applications include heating elements, pilot lights, pump control, and alarms. Industrial relays are typically NEMA or IEC rated.

  • Electromechanical
  • Interval Relays
  • Mercury
  • Monitoring Relays
  • Reed Relay
  • Sockets
  • Solid State


Simple idea. Endless variations. At the most basic level controls whether a circuit is open or closed. Choose your actuation method (push, slide, turn), poles (how many circuits can be controlled) and throws (how many positions the switch has). One of the most overlooked characteristics is feel — how the switch feels to the user when actuated.

  • Emergency Stop
  • Foot
  • Key
  • Limit
  • Power
  • Rotary
  • Selector
  • Toggle

Terminal Blocks

A modular method for fastening two or more wires. Usually IEC or NEMA rated. Things to consider when specifying terminal blocks are material (thermoplastic or ceramic), ratings (current, voltage, wire size), clamp (screw, cage, or spring), classification (IEC or NEMA), and marking (printed, labeled)

  • Ceramic
  • DIN Rail
  • Distribution Blocks
  • Screw Clamp
  • Spring Clamp


Provide accurate and repeatable timing and monitoring operations in all types of automation and industrial environments.

  • DIN Rail

Step down voltages. Convert a primary (input) voltage to a secondary (output) voltage. Common variations include open style or encapsulated, NEMA or IEC, and touch proof covers. Important design characteristics include steady-state power (VA), inrush power (VA), and inrush power factor (PF).

  • Buck/Boost Transformers
  • Class 2 Transformers
  • Current Transformers
  • Encapsulated Industrial Control
