The 45U Trigger Board is used for 115 volt applications. It can be configured for full-wave (AC) or half-wave (DC) output. DC modes can be selected that utilize either the top half or bottom half of the AC sine-wave. Opposing half-wave (DC) settings can be chosen when used in Dual and Triple controls to equalize line current draw via opposing dip switch settings.
The TB23 Trigger Board is used for 230 volt applications. It can be configured for full-wave (AC) or half-wave (DC) output.
