Ordering Information:

TBC Series is a Multi-high power capacity with prllel operation output mode with 300kW - 1MW of unit capacity, the total capacity can be expanded up to 10MW by series-parallel connections. Multiple DC power supply panels can individually operate in single mode to configure multi-channel output, or in Master/Slave mode to configure single-channel output with combined capacity. TBC series provide real-time battery and PV simulation function with fast response time of less than 1 ms. TBC series provide grid-regenerative DC electronic load function, which is applicable for testing fuel cell stack or fuel cell engine system, etc.

Type Recommendation

High Power Scalable Design
TBC series apply DMPS (Digital Matrix Parallel System) method for large-scale parallel expansion and
stable power supply, which enables capacity expansion up to 10MW by connecting in parallel in 1MW
increments from 300kW minimum through high-speed optical fiber communication m ethod. In
particular, parallel connected panels can be used in multi-output mode by separating outputs
according to user needs, enabling multiple test equipment to be tested at the same time, maximizing
user convenie nce and sa ving costs.

Output Expansion up to 10MW with Master / Slave Control

Auto Ranging

The auto ranging function automatically controls voltage and current through the programmable DC power supply to maintain the rated output over a wide operating range. That is the higher voltage is available at lower current and vice versa, allowing the DUT to be tested under different voltage/current conditions with a single DC power supply.

In addition, it supports smooth and ultra-fast automatic switching with the bidirectional Automatic source & load function. The overshoot of voltage or current can be effectively controlled without any delay in the transition between the two states of source and load.

CV/CC Priority Setting Function

CV (constant voltage) priority / CC (constant current) priority mode can be selected and set.

Suppression to Overshoot with CC Priority Mode

With the TBC series power supply, the CC priority mode can effectively respond to load variat ions.
This mode suppresses momentary current spikes when the load suddenly changes its resistance, thus ensuring stable protection for sensitive loads.
Configuring the power supply in CC priority mode allows for voltage adjustment according to load
changes, maintaining a stable current. This effectively protects sensitive loads such as high-power
laser diodes and minimizes the risk of damage due to overshoot.

Current Overshoot in CV Priority Mode

In CV priority mode, the power supply prioritizes maintaining a constant output voltage. However,
sudden load variations can cause momentary current spikes, posing a risk of damage to sensitive
loads. Therefore, configuring the TBC series power supply in CC priority mode enhances load stability
and prevents damage caused by overshoot.
