This classic form of plasma excitation makes use of direct current (DC) generators.
When cost is a factor, this technology offers one of the most economical solutions. These generators, which are used mainly in single cathode systems, are used in DC bias processes such as for metallic mode sputtering.
HUETTINGER Electronic offers a broad range of direct current generators for plasma excitation.

DC – UPS Systems for Safety Relevant Installations
With their modular construction, the latest DC – UPS systems in the GTLB/GTPB series from Zentro Elektrik expand the existing comprehensive range of DC – UPS systems for supplying power to safety relevant installations.
The AC/DC systems in standby parallel mode are designed for outputs
from 250 Watt up to 600 Watt and fitted with batteries at the customer’s request. Additional DC/DC converters can be added to the system if more output voltages are required.
A battery control and monitoring module allows to control the charging current and temperature control of the charge closing voltage.
Over and above this, numerous monitoring and control signals are provided via relays, LED’s or potentiometers. A signal relay, for example,
if the charging voltage fails, to switch off the battery on it reaching the closing discharge voltage, to give advance warning of reaching closing discharge voltage with an additional adjustable threshold or individual limitation of the battery charging current to prolong battery life, and
many more. LED displays and adjustable potentiometers provide for comprehensive signalling and the ability to adjust the maximum charging voltage or the defined point of battery switch-off.

Characteristics
DC Power Supplies R&S NGSM are versatile supply and measuring units for testing electronic car components by simulating real operating conditions. In addition to a wide field of car electronics, it can be used in mobile radio, car hifi applications and mechanical engineering. Due to its compact design, the units take up only one half 19" width. A 19" adapter is available for mounting the R&S NGSM into test racks.
Application-specific characteristics
Car electronics
R&S NGSM is a precise and, thanks to its versatility, an extremely economical tool for use in the production of electronics. With the aid of an IEC/IEEE bus or RS-232-C interface (optional), the power supply can readily be integrated into in-line production systems. The startup curve in line with DIN40839 can be adapted to other factory standards by reprogramming it. High surge currents typically occur in applications such as central lock-ing or ABS, but with a pulse current of up to 30 A, R&S NGSM32/10 is ideally prepared for these applications.
Mobile radio systems
The high resolution for current measurements allows the maximum operating time of a mobile phone to be accurately predicted; typical voltage drops during the startup of a car - which have to be tolarated by telephones operated at a car net can be simulated.
DC Power Supply R&S NGSM is insensitive to the RF voltage conducted from a device under test or radiated from a nearby antenna.
