Ditek DTK-2MHLP75BWB 75V Surge Protector with Base

The Ditek DTK-2MHLP75BWB 75V Surge Protector with Base is a modular low-voltage surge protection device designed to protect two circuit pairs from damaging electrical transients.

The WB suffix indicates that the DTK-2MHLP75B protection module is supplied with its single-position hardwired mounting base. The module is field replaceable, allowing the protection component to be serviced without replacing the complete wired base.

Product Functions

• Protects two low-voltage circuit pairs
• Designed for 70V speaker and audio circuits
• 75V service voltage
• Includes hardwired mounting base
• Provides line-to-line surge protection
• Provides line-to-ground surge protection
• Uses hybrid TVS/SAD and GDT protection technology
• Provides 20,000A surge-current capacity
• Supports AC and DC circuits
• Field-replaceable protection module
• Uses a modular edge-card connection
• Supports multiple modules with a common grounding point
• 75V Circuit Protection

The DTK-2MHLP75BWB is the 75V configuration of the 2MHLPB Series.

Published electrical ratings are:

Service Voltage: 75V

Maximum Continuous Operating Voltage (MCOV): 90V

Clamping Voltage: 108V

This voltage configuration is particularly useful for protecting compatible 70V distributed speaker and audio circuits.

Two-Pair Protection

Each DTK-2MHLP75BWB protects:

Two circuit pairs

from transient voltage events.

For systems requiring additional protected circuits, DITEK’s modular base architecture allows multiple protection modules to be combined. Multi-position bases are available for configurations protecting up to 10 pairs with a common ground point.

20kA Surge Current Rating

The DTK-2MHLP75BWB has a published surge-current rating of:

20,000A

This represents the maximum surge-current capability specified for the 2MHLPB Series under the manufacturer’s test conditions.
