32704 AC & DC Electronic Load
- 3270 Series is suitable for the step, square and sine wave of the AC Power device test, especially for the uninterruptible power supply UPS, Inverter, fuses, circuit breakers, power regulator AVR, battery, AC / DC power supply / components ... and so on, absolutely is the best test solution in the market.
- Master / Slave has 2 operating modes
2. 3PH mode is for 3 phase application, three 3270 series can be connected for three phase Δ or Y connection, the setting current value (single-phase current value) will be sent to each Slave unit automatically, the user does not have to set each unit.
- 4 digit V / A/W Meter，display the Voltage（Vrms, Vpeak, Vmax., Vmin）、Current （Irms, Ipeak, Imax., Imin.）、Watt, Voltampere （VA）、Frequency、Crest Factor、Power Factor、Total Harmonic Distortion of Voltage（VTHD）, Voltage Harmonic（VH）、Total Harmonic Distortion of Current（ITHD）, Current Harmonic（IH）
- CC, Linear CC, CR, CV, CP and AC Rectifier Load mode
- Voltage Optional : 425Vrms / 600Vdc ( except 3273 / 3274)
- Crest factor range : 1.414~5.0
- Power factor（PF) range : 0~1 lead or（-1~0）lag
- Built-in function test modes include UPS Efficiency, PV Inverter Efficiency, UPS Back-up time, Battery Discharge time, UPS transfer time, Fuse/Breaker Trip/Non-Trip, Short circuit , OCP, OPP test modes
- Turbo mode is able to increase to 2 times the current and power of electronic load in a short period which is the most suitable for Fuse / Breaker test and short circuit, OCP, OPP test of AC power supply
- Time measurement can be applied to batteries, UPS, fuses and circuit breakers and other tests
- Eight units parallel up to 90KW and three-phase △ or Y load connection can be synchronized control by one master unit
- Support on-load boot; at first set Load ON to support on-load boot, inverter or uninterruptible power supply is turned on directly with the set load current, used to verify whether the starter is stable when the Inverter is connected.
- Supports the loading and unloading angle control; the loading and unloading angle control, the full range of 0-359 degrees can be set to verify whether the Inverter output voltage transient response is stable when the actual electrical plugging and unplugging, and whether Overshoot/Undershoot is within the allowable range.
- Support positive half-cycle or negative half-cycle loading; used to verify whether the Inverter output voltage remains stable when the actual appliance has only positive half-cycle or negative half-cycle load current.
- Supports SCR/TRIAC current phase modulation waveforms, 90 degree Trailing edge and Leading Edge.
- Frequency Range : DC, 40~440Hz
- Voltage and current monitoring
- Can be controlled by external voltage for CC, Linear CC, CR, CV, CP operating modes
- Protection against V, I, W, and℃
- Optional interface：GPIB、RS232、USB、LAN
- The most complete measurement capabilities
