TMOV34S Thermally Protected Varistor - Littelfuse

TMOV34S Thermally Protected Varistor - Littelfuse

TMOV34S Thermally Protected Varistor - Littelfuse

"It consists of a 34mm square format varistor element ( MOV) with an integral thermally activated element designed to open in the event of overheating due to abnormal over-voltage, limited current conditions as outlined in UL1449 ...

The device has a third lead, an indicator lead, which may be used to indicate that the MOV has been disconnected from the circuit."

ROV Metal Oxide Varistors Raychem Tyco

"The ROV device's high current-handling and energy absorption capability, fast response, and low cost can make it suitable for use in line voltage applications."

"An ROV device is a varistor fabricated using a Zinc Oxide (ZnO) powder, sintered with other metal oxide ceramics. The resulting
structure is a polycrystalline ceramic that consists of distributed ZnO grains, separated by other metal oxide ceramics."

"A varistor is a variable resistor-a voltage dependent, non-linear device whose resistance decreases as the voltage applied across the device increases. "

Handy Calibrator Model CA51 - Yokogawa

Handy Calibrator Model CA51 - Yokogawa

"The CA71 Handy Calibrator is a small, lightweight, multifunction calibrator that can simultaneously source and measure voltage, current, resistance, TC, RTD, frequency, and pulse signals."

Handy Calibrator Model CA51 - Yokogawa

Features Include

Simultaneous signal generation and measurement capability:

The CA71 lets you handle regular tests on TCs, RTDs and various other types of sensors and instruments, as well as operation checks when a problem has occurred (TC and RTD measurement functions are CA71 only.)

AC voltage (including supply voltage) measurement capability:

In cases where numerous signal converters and other devices are mounted on a rack or panel, the Handy Calibrator can be used to check the input and output signals of each device, while simultaneously checking the power supply.
