HZDL-2500Q-Temperature rise test system

Current Output System:

Utilizes a three-phase current source (0-2500 A).

Comprises multiple parallel current source groups; output current per group is independently adjustable.

Output phase angles of all groups are strictly synchronized (identical A-phase angle, identical B-phase angle, identical C-phase angle across all groups).

Total current applied to the incoming cabinet equals the vector sum of currents from each group.

HZDL-7500Q Temperature rise test system

Current Output System:

Adopts a unidirectional three-phase current source (0-7500 A).

The system consists of multiple parallel current source groups; the output current of each group is independently adjustable.

The output phase angles of all groups are strictly synchronized (i.e., the phase angle for A-phase is identical across all groups, the phase angle for B-phase is identical across all groups, and the phase angle for C-phase is identical across all groups).

The total current applied to the incoming cabinet under test equals the vector sum of the currents from each group.

Maximum Output Current:

AC Single-phase: 7500 A

AC Input Specifications:

Connection: 3Φ4W (Three-phase, Four-wire)

Voltage: 380 V ±10%, 50 Hz ±2%

Maximum Input Current: 263 A

Output Specifications:

Connection: 3Φ4W (Three-phase, Four-wire)

Open Circuit Voltage: 0-8 V

Output Current:

Split-phase AC 0-7500 A (Per phase, independently adjustable)

Supports three-phase simultaneous output or single-phase output modes.

Supports manual output and automatic output control modes.
