Surge protective device module (SPD-M) is an onboard lightning protection module that integrates functions, such as thermal protection, overvoltage protection, and remote signaling, and others. A single module can meet common-mode, differential-mode or full-mode protection requirements.SPD-M, an integrated solution, can simplify the design and selection of surge protection modules for users, and is suitable for surge protection of low-voltage AC or DC power supply equipment. Surge protective device module (SPD-M) has the characteristics of small board space, high level of integration, and complete protection functions and solutions.

U_p

Usage

1. Frequency range is from 47 Hz to 63 Hz.

2. The voltage applied continuously to the SPD module must not exceed its maximum continuous operating voltage Uc.

3. When atmosphere press is from 80 kPa to 106 kPa, the related altitude shall be from 2000 meters to - 500 meters.

4. Do not touch the product body or pins directly when power is on, to avoid electric shock.

Replacement

As SPD module is a non-repairable product, for safety sake, please use the same type of SPD module for replacement.

Storage

Do not store SPD module at high temperature, high humidity or corrosive gas environment, to avoid oxidation of the lead wires. Use them up within 1 year after receiving the goods.

Installation Position

Do not install SPD module to the place that may suffer severe vibration.

Recommended Hand-Soldering Parameters

Note:

The wave soldering parameters are for reference only. Before SPD module is for practice usage, relative validation is recommended.
