Note
For 115 Vac operation, please contact
Power interrupts
Menu settings, all parameters and the sound speed profile are stored on the Operator
Station's harddisk during operation, so operation can continue after power interruption.
However, the file system may be damaged, so the use of an uninterruptable power supply
(UPS) is highly recommended.
Environmental and EMC specifications
The system meets all requirements of the IACS E10 specification. The Transceiver
and Preamplifier Unit meet the additional stronger requirements of the IEC 60945
specification.
The Operator Station and the LCD monitor are both IP22 rated. The Transceiver and
Preamplifier Unit are IP54 rated.
Standards
EMC Noise emission: EN55022 (Class A)
EMC Noise immunity, voltage spikes: EN55101
