VERSATILE DC POWER SUPPLY

Variable Range Output

  • Voltage range: 35V to 1000V
  • Current: 1A to 108A
  • Power: 360W to 1080W
  • Available for the pulse

Wide range output is possible with "Turbo function" installed.

TB series is a programmable DC power supply with distinctive turbo function which realizes three times wider coverage of output voltage and current in comparison to conventional DC power supply with equivalent output power.

All TB series models allow flexible voltage and current output within their rated power, which means users do not need to find a separate power supply for different requirements. Thus, a single TB unit can be used for a wider range of applications.

In addition to its wide output range, the TB series is designed to deliver exceptional overall performance. It features a power factor correction circuit with a power factor of 0.99, a fast and accurate four-digit display panel, and a precision rotary encoder. Its high energy efficiency contributes to reducing the user's CO2 emissions.

Digital communication* with LAN, USB, RS-232C, RS-485, and GPIB is optionally available, best for automatic measuring or integration to production equipment.
* A conversion adapter or additional option is required separately.

FEATURES

  • Setting and output of pulse/ramp operation without a Personal Computer
  • It realizes wide-range output by installing a turbo function.

Function for Pulse & Ramp and Master Follow (Tracking)

Output control as next A to D is possible.

A. Pulse (Step) Sequence Function

The Sequence function lets you generate complex voltage and current patterns by automatically cycling through settings stored in memories a, b, and c. You can run the sequence continuously or for a specified number of cycles. By setting the duration of any step (a, b, c, or off) to 0.0, you can easily skip steps to create custom test patterns. This flexibility is ideal for product evaluation and reliability testing.

A. Pulse Sequence

The parameters ta, tb, tc, and toff can be set to 0.0 s, or from 1.0 s to 99.9 h.

B. Ramp Function

The Ramp function provides linear control to gradually increase the output to a set voltage/current, or decrease it to zero. This feature is useful for applications that require a slow power-up or power-down.

* The ramp operation can be applied to: Voltage and Current, Voltage Only, or Current Only.

B. Ramp

t1 and t2 can be set respectively in 0.0s to 999.9s.

C. Combined Sequence and Ramp

For advanced control, the Sequence and Ramp functions can be used together. This allows you to create complex profiles by smoothly ramping the voltage and/or current between the discrete steps defined in memories a, b, and c. The entire waveform can be run continuously or for a pre-set number of cycles, making it a powerful tool for various testing scenarios.

C. Pulse Sequence + Ramp

t1 and t2 can be set from 0.0 s to 999.9 s, while ta, tb, tc, and toff can be set to 0.0 s or from 1.0 s to 99.9 h.

D. Master Follow (Tracking)

Master-follow is a function that allows a slave equipment to follow the output status of the master equipment in a master/slave connection. The output status of the master equipment is transmitted to the slave equipments to enable interlocked operation. The master and slave can be set to different modes of operation, allowing for complex testing.

* The Master Follow function is available only with Matsusada Precision's original digital interface.

D. Master Follow
[NOTE]
(1) This function cannot be used in conjunction with “Delayed Trigger Function”
(2) Time accuracy in sequence operation is ±0.5%. Take care when using the product in long-term running operations.

Variable Internal Resistance Function (in CV mode)

By setting the internal resistance value as any value, it causes a voltage drop due to load current.
This is the best fit for simulating batteries, solar cells/panels, and fuel cells.

(Programmable range of the internal resistance value is 0 Ω to rated voltage/rated current)

Example
Variable Internal Resistance Function (in CV mode) | TB series | Benchtop DC Power Supplies | Matsusada Precision

Function for Multi-setting

Three sets of voltage and current values can be stored in memory, in addition to the standard preset.
It is very useful for experiment to collect repeatedly data and inspection of products.

Two Modes for Lock

Either of two modes can be selected and set, "Full Lock," which locks all operations from the front panel, or "Normal Lock," which locks only output ON/OFF. (The above two modes can stop the output emergently with the power switch.)

CC/CV Preferred setting

CV (Constant Voltage) or CC (Constant Current) preferred mode can be selectable. When a load is such as a diode whose resistance value can dramatically change at a certain point, an overshoot of current may take place if the power supply is triggered under CV mode.

The TB series can help suppress this overshoot by choosing the CC mode trigger as a preference. This feature is highly valued for lowering the risk of damaging expensive loads typically such as high-power laser diode modules.

CV priority mode
Overshoot created at the change from CV to CC, depending on load nature. CV Preferred setting
V-I characteristic of diode
CC priority mode

Sink Current Suppression

When supplying power to loads with capacities like batteries and capacitors, the sink current suppression is used to reduce the reverse current flowing from the load to the unit in order to prevent a voltage drop on the load as the output is OFF or the set voltage is lowered.

sink current suppression

Note: Reverse current cannot be controlled and stabilized. Connect a dummy resistor or reverse current prevention diode when a load of the reverse voltage is equal to or higher than the rated voltage (inductive loads, regenerative motors, etc.).

Delayed Trigger Function

The delayed trigger function allows it to delay the time for output start and output stop, and work based on it during OUTPUT ON/OFF. The delayed trigger function can be used when 1 unit of TB is used, of course. The delayed trigger function can also be used when output voltage/output current are set individually by connecting several Matsusada Precision power supplies using master/slave connection terminal.

  1. This function can not be used with Function for Pulse & Ramp sequence and Master Follow together.
  2. Can be connected to up to 16 units.
  3. R4K-36 series, R4K-80 series, RK-80 series, RK series, and REK series.
  4. Only for slave-local. In the case of the slave remote control, the exact same model of power supply needs to be used. Also, in the case of slave-local, each output voltage and current can be set individually. In the case of slave-remote, output voltage, and current can be set with a one-control function in which each slave unit follows the master unit setting.
Delayed Trigger Function

*t1 to t8 can be set in the range of 0.0 to 99.9 s.

Dual Tracking and Multi-Output

By connecting power supplies to make the output of it become positive and negative at master/slave, the output of positive and negative can be controlled at the save time. (Dual tracking control) Multi-output can be configured in combination with actions of local mode and of dual tracking. Positive and negative voltage output and optional output voltage set on a local slave are outputted in synchronization with the ON of the master unit.
* As for dual tracking control, models at output voltage exceeding 250 V are not available with the function.
