B+K precision adds a 4-channel, ±1500 VDC input module to its DAS1800 data recorder.

Today’s electric vehicles operate at voltages approaching 1000 VDC, engineers need to monitor and record those voltages during tests. to that end, B+K Precision has added the D18-HVM4 high-voltage, 4-channel input module to its DAS1800 modular data recorder. The D18-HVM4 adds four channels capable of measuring DC voltages to ±1500 V and AC voltages to 1000 VRMS.

Each of the four channels uses two BNC connectors for differential measurements. The module has 16-bit resolution and samples at up to 1 Msa/sec with 10 MΩ input impedance.

The DAS1800 holds up to 10 input modules. Other modules include:

• 4-channel, ±600 VDC, 1 MΩ input impedance.
• 4-channel, ±600 VDC, 10 MΩ input impedance.
• 8-channel ±48 VDC, multiplexed, 5 ksa/sec, 2 MΩ input impedance.

The DAS1800 also measures temperature and it provides +3.3 V, +5 V, +12 V, or +24 V excitation voltages for sensors. It can display all channels on its 15.6-in. display and store data on its 2 TB solid-state drive (SSD). It’s AC-line powered with a battery option for remote monitoring, crucial for EV testing.
