60KS200C & 90KS200C
BI-DIRECTIONAL TRANSIENT
VOLTAGE SUPPRESSORS
SCOTTSDALE DIVISION
DESCRIPTION
These devices are bidirectional Transient Voltage Suppressors (TVSs) for shipboard
equipment and power servicing equipment where large voltage transients endanger
voltage sensitive components. It meets all applicable environmental requirements of
MIL-S-19500 and is consistent with MIL-E-16400. Designed with MIL-STD-1399
Section 300A (Interface standard for shipboard systems, Electrical power, alternating
current) as the controlling specification. The subassembly components can also be
tested or screened for military requirements prior to encapsulation into the complete
module. The screening would consist of 100% TX level environmental testing per
MIL-PRF-19500/507A (Par. 4.3). For ordering these options, use the following suffix:
H1 – Submodule Screening
H2 – Submodule and Module Screening
H3 – Submodule and Module Screening
& Module Group B & C lot testing
The individual submodules can also be selected for lower or higher voltage as well as
increased power capability compared to the example 200 volt 60 and 90 kW herein.
