The EMHEATER Variable Speed Drives (VSDs) and Solar Drives include 35 types of warning/protection functions. In case of a fault, the protection function will be triggered, the inverter will stop output, and the faulty relay contact of the inverter will … Continued
How do Solar Drives Work? Solar Inverters All solar powered systems require a Solar Inverter to operate AC powered equipment and appliances. A Solar Inverter is a device that converts direct current (DC) generated by solar panels (or other alternative … Continued
How do Variable Speed Drives (VSDs) Work? AC induction motor speed depends on the number of motor poles and the frequency of the applied power. When operated from a constant frequency power source (typically 50Hz in South Africa), AC induction … Continued
Solar Drive vs VSD AC pumps are usually used for high volumes of water supply and require well-regulated AC power (usually 3-Phase). Using a Variable Speed Drive (VSD), pump motor efficiency can be increased, and electricity use can be decreased … Continued
What is the difference between Variable Frequency Drive’s (VFDs) and Variable Speed Drive’s (VSDs)? There are two primary methodologies for controlling electrical motors with subtle differences: – Variable Speed Drives (VSDs): Controls the speed of a motor by changing the … Continued
