Product Overview:
HSM340 Synchronous Module is specially designed for automatic parallel of 400Hz system genset. According to the pre-set parameters, the module can automatically complete genset parallel condition detection (volt difference, frequency difference and phase) and send parallel signal when the conditions are well prepared.

HSM340 Synchronous Module applies to the occasion where it can synchronize generator to the bus. The module is simple to operate, easy to install and widely used on ship genset and land genset.


Suitable for 3-phase 4-wire, 3-phase 3-wire, 2-phase 3-wire, single phase 2-wire power system with 400Hz frequency;

Adjustable potentiometer allowing to set the main parameters about synchronization;

Operating parameters can be set via PC test software. LINK port should be connected to computer via SG72 module (USB to LINK);

4 relay outputs, 2 of which are used for speed UP output and DOWN output; 1 SYNC relay is used for sync close output, and 1 STATUS relay is used for status output after close;

1 INH “inhibit sync close output” digital input; when it is active and gens synchronizes with bus, the SYNC indicator will illuminate and sync close relay is inhibited to output;

Wide power supply range DC(8~35)V;

35mm guide rail mounting;

Modular design, pluggable terminal, compact structure with easy installation.
