We manufacture standard,
OEM, and custom trigger generators for our switchgear. Standard trigger
generators are designed to fire our trigatron switches and consist of (1) a PG-103D control
unit, (2) FO-xx fiber-optic link where xx equals the length in meters, and (3) THD-series trigger head with fast trigger
transformer. Each control unit can fire up to 4 trigger heads with internally programmable delays. Operating modes include
single-pulse (manual fire), external trigger, and internal oscillator for repetitive firing. TTL outputs (sync and complement
sync) are available for use with external instrumentation such as an oscilloscope. A recharge command signal on the rear panel
(gate) is provided for synchronizing and controlling an external constant-power charging supply. Fiber-optic cables are
available in standard 10- and 20-m lengths or custom lengths by special order. Fiber-optic links eliminate the effects of
electrical noise at the control unit. The trigger head consists of a trigger module and proprietary trigger transformer with
interconnecting cable. When ordered with one of our trigatron switches, the trigger circuit is factory wired for your
application thus affording plug-and-play operation. Click on the links in the following table for detailed specifications.

Special options on a custom or semi-custom basis are available as follows:
- Power Suppy Interface. This interface
provides all control and monitor functions for most modular constant-power supplies, including
voltage set-point, voltage metering, and fault status. We require a description of your power
supply, including manufacturer, model number, and interface pin-out.
- Interlock Logic. Interlock status boards
are available that interface with the trigger generator and power supply to insure safe operation.
Pricing for standard trigger generators may be obtained from the links given on our
Sales page. Specifications are subject to change without notice.
