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.
The TB series all allow flexible voltage and current output within its rated power, resulting in users not to require to search for power supply with unnecessary wider rated voltage and current. Thus single TB unit can be used for much wider user applications.
Not only it's a wide range of output, but the general performance of the power supply is pursued to achieve overwhelming quality, resulting; in a power factor correction circuit with 0.99 power factor, speedy and accurate four-digit display panel as well as the adoption of the precision rotary encoder. TB series is high energy efficiency contributes to user's reduction of CO2 emission.
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.

Functions
Images of Output Range
With the turbo function, a wide range of voltage and current output compared with conventional DC power supplies.



Function for Pulse & Ramp and Master Follow (Tracking)
Output control as next A to D is possible.
A. Pulse
Sequential operation is possible by using voltage and current set on each memory a, b, and c in combination with multi-set function. Not only continuous operation, but also it is possible to specify the times. It is best fit to evaluation tests for products as various operations, like a repeat of a and b only or a repeat of b, c and off only, are enabled by setting time of memory a, b, c and off to 0.0.

ta, tb, tc, and toff can be set respectively in 0.0s, 1.0s to 99.9h.
B. Ramp
It enables to make ramp action up to the set voltage or current (or from the set voltage or current to 0 V or 0 A). It is useful to like to rise (reduce) voltage or current slowly.
It helps sensitive electrical load not to get damaged by an overshoot.
* As for ramp operation, you can select "Doth of set voltage and current", "Voltage setting only", or "current setting only".

t1 and t2 can be set respectively in 0.0s, 0.1s to 999s.
C. Pulse + Ramp
It is also possible to use pulse combined with ramp action.
If a multi-set function is combined with the too, it is able to make pulse action by using voltage or current set on memory a, b, and c. Not only continuous operation, but also it is possible to specify the times.
It is useful in various aspects as it is possible to rise (reduce) voltage or current slowly up to three set values.

Range of 0.0s, 0.1s to 999s for t1 to t4 and range of 0.0s, 1.0s to 99.9h for ta to tc and toff can be set respectively.
D. Master Follow (Tracking)
With the function, the slave units follow the output signals at pulse and ramp actions in master/slave mode. It is useful for the slave units to output with different conditions from the master unit.
* The master follow function is only available with the standard interface.

- Important point
- (1) This function can not be used with "Delayed Trigger Function" together.
- (2) Accuracy of the timer at sequence action ± 0.5%. Please take care usage at long-running.
Internal resistance value variable function (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)

Function for Multi-setting
3 values for voltage and current are memorized in addition to the usual ones of preset. It is very useful for experiments 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 or CC 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 by CV mode.
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.



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.

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.
- This function can not be used with Function for Pulse & Ramp sequence and Master Follow together.
- Can be connected to up to 16 units.
- R4K-36 series, R4K-80 series, RK-80 series, RK series, and REK series.
- Only for slave-local. In the case of the slave remote control, exact same model of power supply need 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.

*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. Plus and minus output voltage 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.
