Spitzenberger & Spies GmbH & Co. KG products

Frequencies from 1.5kHz … 200kHz can be generated in laboratories and test systems with an output voltage of up to 270V. Testing of electronic components, capacitors and filters. Under voltages and over voltages as well as frequency variations can be simulated. It is possible to test all kinds of electrical and electronic devices (e.g. testing of high frequency measuring instruments).

Frequency range of 15Hz - 1500Hz and an output power of up to 30kVA at cos Phi 0,7 (ind) -1 - 0,7 (cap).

Very fast slew rate >52V/µs at 230Vrms as required by IEC/EN 61000-4-11. Operates from DC up to 5kHz large signal bandwith (-3dB) optional up to 30kHz. Small signal bandwith up to 100kHz. High long-term (1 hour) overload characteristic. High short-term (5-10 min) overload characteristic. Very high peak load ability (up to 5ms). Very low internal resistance.

Due to the climate change the use of regenerative energy sources is promoted increasingly. The use of solar energy is becoming more and more important. The ideal test system for solar inverters consists of a photovoltaic solar cell simulator (PVS), a mains supply system simulator (DM 90000/PAS) and a power recuperation unit (PRU) which reduces the energy consumption of the entire system by app. 70%.

Free programmable I/V characteristic. Simulation of many different solar cells including partly shading is possible. Very fast reaction time on load changings, typically less than 100μs. Real simulation of the 100Hz Ripple on current and voltage of single phase inverters. I/V curve is reproduced very exactly. Simulation of dynamic irradiation, thermal characteristic and course-of-the-day of the irradiation. Evaluation of the static and dynamic efficiency with very precise MPP tracking simulation. Fully compliant testing according to the IEC/EN 50530. Standard Version up to 950V. Low-Voltage Version up to 150V, Micro-Inverter. NEW: High-Voltage Version up to 1500V available. 

In the event of switching off or loss of function of the supervising supply network, islanding networks can appear. Within these the local generator is still driving the supply voltage and supplying the network connected loads without any monitoring and supervision of voltage level and waveshape and frequency of the power supply companies.

Consumes the generated power of the solar inverter and feeds it back into the mains. Reduces the heat exhaustion and therefore the power losses of the system. Increases the sink power capability up to 6 times the nominal value. Without influencing the simulated voltage.

Test Pulses And Voltage Variations According To Iso Standards And Manufacturer Specifications. Test Pulses And Voltage Variations According To Iso Standards And Manufacturer Specifications. The modular simulation system ist very well designed to perform immunity tests with a pulse characteristic and with line coupling injection according to the following standards: ISO 7637, ISO 16750-2, ISO 21848, as well as manufacturer specific standards from Audi, BMW, Daimler Chrysler, Fiat, Ford, GMW, Mitsubishi, Nissan, PSA, Renault, SAE, VW.

The Spitzenberger & Spies simulation system for aircraft supply networks is a modular test system. Depending on the aircraft type and the relevant specification we simulate the 400Hz AC networks with 115V/230V as well as the DC networks with 28V and 270V. In the according standards Airbus ABD0100.1.8/ABD0100.1.8.1, DO160, Boeing 787B3, AMD 24/C the test specifications for aircraft supply systems are well defined.

We use a single-phase simulation system to simulate the supply network of railway vehicles to meet the necessary voltage and frequency values
