Our product SCR Firing and Triggering Cards using Phase Angle Control Technique For Single / Two or Three Phase heater control and DC rectifier. Using synchronized phase angle control technique.Libratherm offers SCR triggering cards model LTC-12, LTC-13 and LTC-15 and LTC-18 , which are designed to fire or trigger back to back connected SCRs using synchronized phase angle control technique. The card accepts analogue control signals of (0-5)/(0-10)VDC or (4-20)mA and provides proportional gate/cathode triggering pulses G1K1 + G2K2. These pulses can be used to trigger back-to-back connected SCRs upto 1000Amps with gate current upto 300mA. The card also provides built in regulated 5VDC supply to connect external potentiometer to manually control the SCR firing. The on card ramp up and ramp down settings allows gradual rise and fall of the voltage levels across the load. Many times it is required to limit the current flowing through the load. Such current limiting feature is available in LTC-13 – for single phase and two phase load. Whereas for 3 phase load, common three phase current limiting is achieved by LTC-18 card. The load current or Line current feedback is derived from the external CTs. This feature is useful for transformer load or inductive loads or for heating elements like Silicone Carbide and Molybdenum Disilicide, which exhibits significant change of resistance with increase in temperature. This feature will restrict the maximum load current to the value set using the on card current limit (CL) potentiometer. On a sudden increase in the current the current trip feature will over-ride the current limit feature and the firing of the thyristor will stop instantly. The trip contacts are available on the terminals.

Features:
  • All these cards can be mounted inside the control panel.
  • Digital and Linear circuit based.
  • Smooth Control On card setting to adjust Ramp Up and Ramp Down.

Usage/ApplicationServer Room/Data Center Temp and Humidity monitor
MaterialABS
Humidity Accuracy+/-3%

Description:

Libratherm offers HTM-3000-i to monitor Temperature and Relative Humidity (T + Rh) value in the Server Room, Data Centre, Ware House, Laboratories etc... It has capability to interface with the Internet and thereby T + Rh parameters can be monitored on any Internet compatible devices like Cell phone, Tablet PC, Laptops or Desk top computers. Such wireless monitoring feature is very useful in the industry to measure and monitor the unmanned remote areas from any part of the world. The web based application can be provided to customize the user interface, which allows user to monitor near real time value of T and RH with Alarm Alerts. In the event of abnormal value of T or Rh parameters, the Email or SMS alert can also be generated and can be forwarded to concern users. HTM-3000-i has built in red and green digital display for local monitoring of T + Rh values, and has built in LED indications for Power ON, Wi-Fi and Server connectivity. It works on 90-240VAC adapter and has built in T + Rh sensor or offers external sensor with 5 meters extended cable.
