The TESLA DRT- 341D series DIN rail three phase four wire energy meters.
With the TESLA product range we have provided a large scale of energy meters on the market suitable for
110V AC to 400V AC (50 or 60Hz). Besides the normal energy meters we also developed our own
pre-paid meters with chip card, chip card re-loaders and a complete PC management control system.
