Used PFEIFFER / BALZERS HGG 2000 #293587874 for sale

PFEIFFER / BALZERS HGG 2000 is a high-voltage, hot-cathode, glow-discharge power supply for use in vacuum pumping systems. BALZERS HGG 2000 is designed for extremely low power losses and optimum performance for most applications. It offers accurate control of the ionizing current to maintain peak ionization within a wide range of pressures, allowing for highly efficient operation. PFEIFFER HGG 2000 is a regulated hot-cathode power supply with an adjustable output current and voltage. It is capable of producing an output current up to 1000 mA, while output voltage range is ranging from 300VDC to 3000VDC. It is designed with a digital voltage and current regulation, allowing for precise tuning of the output. The adjustable output voltage is suitable to power various types of ionizers. HGG 2000 can be operated in either continuous or starting/stopping modes. In continuous mode, the power output is adjusted to maintain constant ionization at all operating pressures. This mode is recommended for continuously operated pumping systems. The start/stop mode is specifically designed for applications where the system is started up from atmospheric pressure. PFEIFFER / BALZERS HGG 2000 is equipped with a temperature-compensated ion current monitor and a temperature-compensated fountain current measuring device. This temperature compensation feature allows for improved performance and control of the ion current at varying temperatures. In addition, BALZERS HGG 2000 is equipped with a soft-start function to avoid overloading the secondary ion collector and to provide protection against arcs. PFEIFFER HGG 2000 features durable construction elements including double-compliant connectors, gold-plated contacts and a reinforced plastic housing. In addition, the unit has a built-in overload protection circuit, preventing damage from excessive current. HGG 2000 is compatible with most shielding gases and can be used both indoors and outdoors. In conclusion, PFEIFFER / BALZERS HGG 2000 is an efficient, reliable and easy to install power supply for hot-cathode, glow-discharge vacuum pumps. It offers adjustable control for high efficiency and low power losses, making it an excellent choice for most high-voltage vacuum pumping applications.
