The SPM-D10 is a microprocessor based synchroniser designed for use on three phase AC generators equipped with speed controls and automatic voltage regulators. Frequency, phase and voltage are automatically matched using either analogue or discrete output bias signals. There is a two line LCD display with a number of features including synchroscope indication, password protection, PC configuration and breaker status indication.

Available variants:

• The SPM-D10/YB – three-phase generator and bus measurement
• The SPM-D11 – load/var sharing
• The SPM-D21 – synchronisation for two circuit breakers and load control
