The TD-1330 is a portable instrument dedicated to on-site inspection of EV AC charging spot, with three-phase AC voltage measurements up to 300 V, three-phase AC current measurements up to 78 A, and AC electrical energy measurement available in class 0.05 / 0.1. The instrument can be combined with TK4720 AC adjustable resistive load to complete the metrology characteristics test and interoperability test of AC charging spot.

Features

• AC harmonic measurement: Harmonics order of 2 to 64 can be detected.
• Power waveform display: Real-time charging curve U(t), I(t), P(t), E(t) display and record, etc.
• Ambient temperature measurement: Built-in temperature sensor for measuring the ambient temperature of the site to correct the working error.
• Clock verification function: Built-in GPS clock module, real-time clock display, and correct the Beijing time of the charging spot.
• Integration: Built-in measurement module, charge control guidance circuit, waveform acquisition and other modules, can complete all interoperability test items of AC charging spots.
• Built-in vehicle control guidance circuit: AC charging spot interoperability test can be completed, built-in L1, L2, L3, N, PE, CP, CC circuit on-off switch and CP ground short circuit switch, can realize the vehicle AC charging interface circuit fault simulation function. Built-in vehicle-side R2 resistance, R3 resistance simulation equivalent resistance simulation function, R2 resistance has adjustment range of 500 Ω ~ 6800 Ω, with resistance value online continuously adjustable with adjustment fineness of 1 Ω; R3 equivalent resistance has nominal value of 500Ω ~ 13000Ω, with resistance value online continuously adjustable with adjustment fineness of 1 Ω. Each contact point has an on-off switch, which can simulate the on-off state of the contact point.
• Waveform acquisition: Built-in 4-channel high-speed waveform acquisition module to ensure long-term operation and zero data loss.
• PWM signal measurement: Measure the frequency and duty factor of the PWM signal on the CP line in the control guidance circuit and display it in real time.
• High reliability: No switches, relays and other mechanical contacts in the current loop, can be overloaded at 2 times the rated current for 5 s.
• Calibration and verification: With dedicated calibration terminals, the device can be calibrated or verified by two methods, and the TK4965 AC charging electrical energy calibration adapter is optional.
