Ultra Slim DC Power SuppliesNEW

New and useful functions and stylish front panel design!

Useful new feature of variable setting range

Set voltage/current value within 80W, then turn on output *Not automatic range change which can output 80W all the time. Resetting is required.

RK-80 series is DC regulated power supply which has two time wider output setting range. For example standard

80W 36V model is enable to set up to 2.2A current (80W 36V), but RK-80 is enable to set maximum 5A, and has

both setting range of 36V/2.2A and 16V/5A.

Further more, the size 1/3, and weight is 1/5 of standard 80W power supply. Featuring OVP, OCP, 3 individual

presets and locking function, RK-80 is high cost performance model.

02

Preset setting is automatically displayed when output is off.

OCP is added for more safety operation.

Quick lock with one touch action.Two selectable lock options.

03

Function to memorize 3 different voltage and current settings in addition to standard preset function.No need to adjust the output when different setting, and convenient function for production inspection process or testing which require frequent data taking.

Lock all the function other than reset lock mode, and effective for purpose to avoid mis-operation when controlled.

Function to output ON/OFF of total 32 units from one master unit. (when master/slave)

It is possible to delay the ON/OFF time, and simultaneous ON/OFF setting is possible as well.

Ideal function for application which require time delay for ON/OFF setting.

Full LOCK Normal LOCK

Lock voltage and current setting dial, and effective for purpose to avoid changing output setting by mistake or when easy emergency stop is required.

Function to select two different lock functions for two different purpose."Full Lock" locks all the function on front panel, and "Normal Lock" locks all the function except for ON/OFF. "Full Lock" mode shall be good in case mis-operation have to be completely avoided, and

"Normal Lock" mode shall be good in case to avoid mis-operation but secure the way for emergency stop of power supply. You can select the best mode according to your level of "Security", (in both modes, emergency stop is possible with Power Switch.)

[caution] Total output voltage is to be up to 250V. Therefore for models with output voltage of over 250V, series operation cannot be conducted. Output current is to be the smallest current of those.

Please keep all the settings of voltage the same. Output current will be the summation of each current.[caution] Please keep OVP level of power supply maximum to prevent any damage.

[caution] In case of +- operation, the remote connector is connected to negative output terminal. So never connect other remote control to the connector.
