Our special developments
|
|
| The 4.5 MHz HF coupler transfers control impulses to the DC-isolated output stage. This output stage is fitted with modern IGBTs switches with a slew rate of up to 50kV/µs. Even fast optocouplers – up to 15kV/µs – were too slow for this. |
|
|
| The DC/DC converter supplies all 8 auxiliary supplies in the unit. Important from a safety point of view is the a high level of isolation voltage (3.8kV) between the auxiliary supplies, as well as the high level of operational reliability in the event of undervoltage. |

Product description
The V207 high-power amplifier series is a universally usable servo amplifier with extensive monitoring which can be specifically configured to customer needs. Clean DC voltage at the output is achieved by L/C low pass filtering in the output stage.
This ingenious concept brings together a variety of special features:
 |
Output voltage lies between +-100V and 600VDC |
|
Output current of + 40 to 100A |
|
Remote-controlled peak current limitation |
|
True I²t current limitation is variable, whereby |
| |
Continuous currents and peak currents can be adjusted separately |
|
Underlining embeded current controller |
|
Total DC isolation of control unit, and |
| |
the output stage, resulting in freedom from interference at control level |
|
A Boucherot damping network is provided |
|
High power brake stage is provided |
|
Extensive monitoring
Improved diagnosis for safe applications and therefore also a high level of operational reliability. This is achieved by using multiple monitoring of specific conditions:
 |
| U>MAXS: |
Overvoltage *S |
| U<MIN: |
Undervoltage |
| UVWDEF: |
Supply phases |
| IREFLIM: |
Current limitation active |
| I²t: |
Effective current reached |
| I²tS: |
Effective current reached *S |
| I>MAXS: |
Current exceeded *S |
| REGDEFS: |
Controller faulty *S |
| TACDEFS: |
Tacho faulty *S |
| T>MAXS: |
Temperature exceeded *S |
| T>WARN: |

Monitoring displays
Operating conditions are monitored separately and stored. Furthermore, by setting jumpers the customer can decide whether errors should be reported or whether they should immediately lead to shutdowns. |
