DDDL-200E three-phase current generator (referred to as the three phase boost converter), our company developed the development of test equipment, which combines the advantages of similar products at home and abroad in a body, and adopts the technology of numerical control, anti-interference ability strong, and a generation of up flow is compared, because of the low power consumption and large capacity self coupling voltage converter and high permeability core making, with the advantages of high output power, small volume, light weight, etc.. Mainly used for thermal relay, motor protector, contactor, breaker, air switch, switch cabinet, circuit breaker, protection screen check.

PVC panel with beautiful appearance

Direct current, easy to test observation and record.

Measurement accuracy of 0.2

Power, small size, with a strong load capacity

Small size, light weight, the volume of only 30% to 70% of similar products, very convenient to carry.

4 operational aspects

(1) the connection is completed, should check to see whether there is a connection error, the connector is good contact.

(2) in the process of testing, such as flint, and boot without any display abnormal phenomenon, should immediately shut off the power and re check the wiring.

(3) in the actual connection, the current output terminal should form a loop, or the instrument will not output current.

(4) a random output wire of the current lift, and the output of the external copper wire is selected by 10A/mm2. (standard two 3 meter test line)

(5) the equipment capacity is based on 5 minutes of short-term work design, such as for batch test, the working time should be less than 2.5 minutes, wait 10 minutes, and then the next work. If the temperature rise (30 minutes -24 hours) should be prepared in accordance with the long-term working temperature.

1 name and classification

(1) Name: SDDL-200E large current generator.

(2) the environmental groups: belong to GB6587.1-86 "electronic measuring instruments environmental tests program" in group III instrument (can) for use in an outdoor environment.

2.1 input voltage: 380/220V 50Hz AC three-phase four wire

2.2 power: 1*3 2KVA only 3 phase 2KVA a group

2.3 output current: AC0 ~ 200E stepless adjustable, panel with LCD liquid crystal current meter

2.4 output voltage: (>5V)

2.5 output waveform: the output current is the standard sine wave, the burr is small, is better than the power system requirements index standard, the ripple coefficient is less than 0.3%. Standard sine wave.

2.6 measurement accuracy: (using the 0.2S material) is actually around 0.3, the current can be smooth and smooth continuous adjustment, the accuracy is higher than 0.5. The current and voltage meter shows the true effective value, high precision, high stability.

2.7 output current mode: the true and effective value can be adjusted continuously;

2.8 current stability: 0.2%

2.9 structural forms: one

2.10 connection mode: according to the requirements

2.11 current stability: 0.2%;

2.12 protection settings: over current, over voltage

The 128*64 dot matrix LCD display data, more intuitive, more efficient reading (the only)

The instrument display lock function, especially for in transformer ratio test can be more accurate and faster reading (the only)

The 485 communication function, the experimental results can be uploaded directly or use U disk storage instead of manual records (the only)

The measurement of polarity, transformer polarity automatic measurement, without a separate experiment (the only)

The chronograph 0.01S-9999.999S liquid crystal display (the only)

We used a beautiful PVC panel, the panel is more wear-resistant

The measurement accuracy of 0.2 or 0.1

The big power, small volume, strong load ability

The small size and light weight, the volume is only 30% ~ 70% of similar products, very convenient to carry.

The new lock button, more convenient for reading

According to the requirements of the 0-50000A three-phase large current generator
