Product Description:
The model 195H3801 is a frequency converter designed to operate with input voltages ranging from 380 V to 415 V. It efficiently converts electrical power to varying output frequencies for precise control of motor driven systems. The product ensures energy savings and reliability in industrial settings.
This 195H3801 frequency converter by Danfoss operates with an input power of 3 phase with 2.3 A at 50/60Hz. Its robust design features an IP20 rated chassis that ensures protection from dust and environmental factors. It also includes multiple protection mechanisms such as short circuit and earth fault protections for the motor connections. The constant monitoring of intermediate circuit current is employed to prevent overloads and facilitate the switching of motor outputs. The converter is equipped with thermal overload protection which automatically cuts the unit off in case of overheating. It provides several adjustable parameters for optimal performance including an adjustable ramp time from 0.1 to 800 seconds, a quick stop feature with a 1 second duration depending on inertia and adjustable DC injection braking (ranging from 0 - 60 seconds).
The 195H3801 frequency converter offers several technical features that enhance flexibility and control. The maximum wire length from the converter to the motor can extend up to 130 feet (40 meters) with an optional length of 1,000 feet (300 meters). The unit has a high efficiency rating of 94 % at maximum output that ensures optimal energy use. The switching frequency at the line input is 5 times per minute with a start up time of just 2 seconds. The device includes programmable analog and digital inputs, an RS-232 port standard for PC control and outputs that can be programmed for multiple status or alarm indications.
