Pulse width can be programmed with a external 50 Ohm cable through two GR-874 50-ohm connectors. Max . allowed impulse width is 50nS. The internal power supply allows 50Vpk and with ext. PWR max. 300Vpk is possible! | ||
The special feature of the device is, that the switching action is made directly be a mercury-reed contact. Frequency and life time was therefore fairly short. About 600Hz and 200 hours. So, forget to shut down over weekend and some holy-days, needet a replacement of the reed switch. Be aware during servicing, the thermal breaker is on full mains and has no protection cover! | The special feature of the device is, that the switching action is made directly be a mercury-reed contact.
