Product Description

TK3300 Installed Three-Phase
Standard Energy Meter

1. Summary

The TK3300 miniature installed three-phase standard energy meter is a standard energy meter with the same physical dimensions as conventional installed three-phase energy meters. TK3300 is specially used for calibration or intermediate check of three-phase energy meter test bench or assembly line devices, and can complete testing items such as basic errors and multi-channel output consistency.

 

2. Features

1. Accuracy class 0.01 and class 0.02 are optional.
2. There are two types: direct connection and connection via transformer (indirect connection).
3. Voltage measurement range: 288 V (direct connection), 144 V (indirect connection).
4. Current measurement range: 120 A (direct connection), 12 A (indirect connection).
5. Voltage and current support fully automatic switching of range.
6. Phase uncertainty typical value: 0.003° (class 0.01).
7. Lithium battery power supply to avoid the impact of PT power taking on measurement.
8. The battery can last for 8 hours and the charging time is less than 2 hours.
9. Optional manual charging or automatic charging. The automatic charging standard version requires an optional charging system.
10. Supports RS485 and RS232 communication interface.
11. An external display screen (optional) can be connected to display the measured power.

3. Applications

☆  Calibration of Three-Phase Energy Meter Device

1. Install standard meters in batches to conduct calibration or intermediate check on the platform or assembly line equipment.
2. Test items include basic errors, multi-channel output consistency, etc.

☆ Fully Automatic Intermediate Check

1. Equipped with installed standard meters and automatic charging systems in batches
2. Fully automatically complete the intermediate check of the assembly line equipment without manual participation.

4. Instrument Appearance

☆ Instrument Front Panel
picture	S/N	Function
	1	Indicator lights, including pulse indicator lights, alarm indicators, and infrared indicators.
	2	232 Interface, used to configure standard energy mete energy constants, etc.; LCD Interface, used to connect the display screen;
	3	Power button.
	4	Power charging port.
	5	Terminals.

5. Characteristics

☆ Complies with Installed Meter Standard Dimensions
	The size, wiring terminals and pulse lamp position of the installed energy meter are consistent. It can be directly crimped to the meter position of the device without separate wiring, meeting the needs of automated detection.

 

☆ Communication Interface
	Supports RS485 and RS232 communication. Set the energy pulse constant and read the power information. An external LCD display (optional) can be connected to display the measured power value in real time.

 

☆ Automatic Charging System (optional)

The compact size does not affect the automatic operation of the assembly line. It is powered by lithium batteries when working. It can be automatically transferred to the cache area for charging when not working. It communicates and controls with the master control system through Ethernet. It has charging over-voltage, over-current and other fault alarm functions. It has automatic and manual start and stop functions.
