Heavy Duty Vibrating Horn (VHH)

Heavy Duty Vibrating Horn

The Heavy duty vibrating horn is designed to be mounted onto the top of the Cubicle. When the heavy-duty vibrating horn is fitted within the cubicle, a speaker grille is included incorporating a weather-resistant foam barrier to allow the sound to be transmitted whilst providing protection against water ingress. VHH type can also be used as stand alone alarm sound if required, the design is weather resistant without the need for additional protection.

Diode Box (DTB01)

Diode box is use for rectifier, polarity reverse protect, suppressor spike voltage from DC relay coil (Back EMF), blocking DC volt, bypass DC volt etc. Safety from electric shock and easy to install with din rail mount or surface mount. High current circuit, 1A or 3A (specify when order).

Diode Box (DTB01)

Features

10 or 15 Chanel of Diode
High current circuit ( 1A or 3A) )
Low forward voltage drop
High surge current duration
High reliability and stability
Easy install with din rail mount & surface mount.

Digital AC Voltage Monitoring Relay

The AC voltage monitoring relay type E27/59A is a digital relay and designed to monitor a three-phase supply and single-phase supply by checking all phase are pleasant and within set voltage limit. An adjustable time delay is incorporated to avoid nuisance tripping.

Digital AC Voltage Monitoring Relay

When power is applied to relay, the green LED will illuminate (Healthy function) or watchdog function is working. The relay is provided with an adjustable voltage of 80 ~ 100% Un on under voltage unit and 100 ~ 120% Un on over voltage unit with time delay 0 ~ 60 seconds set point.

Under Voltage Function (E27A)

When the monitor voltage falls below the set point, the time delay is started and the red LED (Under voltage LED display) start flashing until time delay has reached the set point value. (The response time of the relay is adjustable between 0 to 60 seconds) Then the red LED stop flashing but steady on, simultaneously with relay energizes or switches to its operating position. The relay will automatically reset once the monitored voltage rises above the set point. When reset, the LED will extinguish at the same time if time delay is not activated.

Over Voltage Function (E59A)

As it is common with all AC voltage monitoring relays, on over voltage unit the relay energizes when the monitor voltage exceeds and the response value is selected, the time delay is started and the orange LED (Over voltage LED display) start flashing until time delay has reached the set point value. Then the orange LED stop flashing but steady on, simultaneously with relay energizes. The relay will automatically reset once the monitored voltage falls below the set point. When reset, the LED will extinguish together in case of time delay is not activated.

Auxiliary Supply

This type is also designed to use with the auxiliary supply source from 90 to 250 VDC. In case of AC voltage from VT or main source are failed, the relay will still working (or status of relay is O.K. when AC input voltage are failed)

Digital DC Voltage Monitoring Relay

The DC voltage monitoring relay type E27D is a digital or microcontroller base relay, commonly used for monitoring battery voltage conditions, but can be used in any applications which dc voltage level is critical too.

Digital DC Voltage Monitoring Relay

The relay is provided with 1 volt step adjustable pickup and dropout voltage with time delay 0 ~ 60 seconds set point. By the way, the relay can be adjusted voltage between 75% – 125% of Un moreover, it has watchdog function to monitor the healthy of itself.

Under Voltage Function

When power is applied to the relay the green LED (Healthy) will start flashing (watchdog function is working), simultaneously the orange LED (P/U) will light up to show that the DC voltage is on normal condition or the input voltage exceeds the pickup setting (P/U). When the monitor voltage falls below the dropout setting (D/O), the time delay is initiated and the red LED (27 – Under voltage LED display) start flashing until time delay reached the set point value. (The response time delay of the relay can be adjusted between 0 ~ 60 seconds) Then the LED stop flashing but steady on, simultaneously with relay energizes or switches to its operating position. The relay will reset once the monitored voltage rises above the pickup set point, the time delay is initiated and the orange LED (P/U) start flashing until time delay reached the set point value. Then the LED stop flashing but steady on, simultaneously with relay reset to normal.

Over Voltage Function

In case of voltage increased to the over voltage set point the orange LED (over) will flashing to show that voltage had reached the set point value until the setup time delay is time out than the orange LED (over) stop flashing but study on and over voltage contact output close or become NC status.
