Ditek DTK-DR24F 24 Volt Surge Protector

Product Description

The DITEK DTK-DR24F is a 24-volt surge protector designed to guard low-voltage control circuits against transient voltage spikes and electrical surges. It is installed in line with 24-volt AC control wiring commonly found in HVAC systems, building automation, and industrial control panels. The DTK-DR24F helps protect sensitive control boards, thermostats, and relay logic from damage caused by lightning-induced surges or switching transients on the power line. Licensed HVAC technicians and electrical contractors install this device as a standard protective measure during system commissioning or service.

This surge protector is suited for residential and light commercial HVAC applications where 24-volt control circuits connect thermostats, zone controllers, or building automation equipment to air handlers, furnaces, heat pumps, and similar systems. It is also applicable in low-voltage control wiring runs exposed to induced surges from nearby electrical equipment or outdoor wiring. Installing surge protection on 24-volt circuits is a common best practice during new equipment installation or after lightning damage events.

Key Features

• Rated for 24-volt AC control circuit applications
• Provides transient voltage surge suppression for low-voltage wiring
• Protects downstream control boards, thermostats, and relay components
• Compact form factor suitable for installation in control panels and air handler cabinets
• Sold as an individual unit for single-circuit protection

Compatibility

Designed as an OEM-style surge protection device for 24-volt AC control circuits typical in residential and commercial HVAC systems, building automation panels, and low-voltage electrical control applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or electrical contractor following applicable NEC guidelines for low-voltage wiring. Disconnect and de-energize the 24-volt control circuit before installing or replacing the device. Mount the DTK-DR24F in a protected enclosure or control panel to prevent physical damage and moisture exposure. Do not install on circuits exceeding the rated voltage of the device.
