2X11reeds

Reeds frequency meters:

---

This vibrating reed frequency meter with one row of horizontal reeds or with two rows of horizontally arranged reeds for connection to one main voltage,vertical arrangements on request
Heat resistance:Case of non-combustible plastic material.
Changeable scale:All scales with printing techique.
The dial plate with different scale,which is at the same intemal value,can be changeable.
But the accuracy is unchangeable

Electronic synchronoscopes:

---

Consumption:3VA
Supply voltage (line/generator):380Vac+20%-40% standard These instruments indicate the synchronism condition when the green LED placed under the arrow in the centre of the dial is lit with a fixed light,and the two yellow phase indication leds are off ,the lighting up of the red leds in a clockwise or anti clockwise sequence indicates that the generator to synchronize is fast or slow regarding the line .if the phase indication LED flashes this means that the generator voltage to synchronize is not present.
SF-96 380V synchronoscope with 380/50Hz supply voltage

Sequence indicator :

---

This indicator is designed for easy testing of phase sequence in three-phase systems with a permissible operating voltage up to 500V.for short connections ,not longer than5 minutes for one test,a push-button switch is placed on the front plate,A Disc with an indicating arrow rotates in the direction of the arrow ,if the three phases are properly connected ,otherwise the disc rotates in the other direction. By changing of two wires. the phase sequence will be corrected to corresponding designation of the terminals.
Model:SF-SI96 SF-Si72
Specification:
Voltage:110-500W
working time:not longer than 5 minutes
