Advantages of a ZERA EMOB test case:
- There is no comparable device on the European market (As of October 2023)
- High accuracy of 0.1% of power
- ZERA is the first manufacturer on the European market to offer a combined test device for AC and DC charging stations
- Our devices have the highest possible safety features, from mechanical locking to high-current monitoring (see list for details)
- Combination of test case and “separate” test device makes the test solutions for e-mobility modular and individual
- Automatic control of the test case via WLAN
- Guided test procedure via a tablet = step-by-step instructions
- Independent of the power supply from its own battery
- The connected test counter is insensitive to interference frequencies up to 150 kHz (Important in the vicinity of charging stations)
Test case & test device in one device
The test device is the standalone test meter from the s2 series (MT310s2 or MT320s2), which can be operated either independently of the EMOB test case or used with any test case from the EMOB series. The test case forms the interface between the charging station and the test meter and ensures safe handling.
Safety features – all suitcases have maximum safety features:
Checking the correct contact of the connected cables
- Detection of the charging cable type
- Electromechanical locking of the connected connections
All cases for DC currents (EMOB200-00, -10, EMOB500):
- Monitoring of DC high-current contacts for overcurrent
EMOB80, EMOB200-00 and -10 and EMOB500:
- Temperature monitoring of the AC contacts and the DC high-current contacts
As soon as the predefined temperature is reached, the charging process is automatically shut down. It can only be restarted after the device has cooled down sufficiently.
