DC Pre paid Energy Meter measures energy consumption & counts down balance in TAKA as per tariff setting. The tariff setting is adjustable after commissioning if required. The meter shuts down load on low balance.
The meter displays useful information’s in LCD like: connected load, operation voltage, balance, cumulative energy usage after each recharge, any fault conditions.
The meter is power limited, this features is particularly useful in applications like solar grid where energy is expensive and to be predictably distributed. The meter has impressive electrical attributes like greater than 99 percent measurement accuracy and very low static loss (3mA).
The recharge code used is based on random numbers and is completely secure to user.
