TS-100 protects four-wire circuits serving computer or other sensitive electrical equipment that could be damaged by lightning or inductive transients. Provides serious protection of communication circuits (1 to 4) for both normal and common mode spikes. The sturdy circuit board (9 x 4.5") uses heavy duty input and output terminals and massive ground intercepts for quenching stray arcs.

Input side: The first level of defense against dangerous high voltage transients on the line is the 300 amp, 1 ms, bi-directional gas discharge tube, in line with power resistors and 600V fuses. High frequency ferrite snubbers help stifle high frequency transients. Protected side: has bi-directional 1500 watt power zeners limit the output to about 10% above the signal voltage level normally carried by the protected lines. Protection is line-to-line and line-to-ground. The extremely high speed (1 Pico sec) and sharp "knee" zeners avoid leakage from the transmitted signal. If the power zener capacity is ever exceeded, the zeners fail by shorting to ground and safely blowing the inline fuses.

The TS-100 carries MSHA's classification for use as a power circuit barrier for a mine-wide monitoring system. The MSHA 600V PCB rating permits system exposure to 600V and fuse ratings to 4 amps. Refer to "BlueBaby" data sheet for more details regarding barrier applications. A 115 VAC version, TS-100-2, is available for protecting 115VAC circuits. The max fuse rating is 15 amps. Insertion resistance is less than one ohm per circuit. The above mentioned MSHA evaluation does not cover this higher powered version. TS-100 modules are installed in a steel enclosure (optional) with space for two units protecting 8-circuits. An earth ground connection with 12 AWG (or larger) copper conductor is required.
