Adjustable DC Power Supply with LED Display, NPS Series

Description

• Full operating protection: overtemperature, overload, and short-circuit protection.
• Compact size, low ripple, light weight, high power density, and high efficiency.
• Voltage stabilization and current limiting with simple operation.
• Automatic switching between constant-voltage and constant-current modes.
• Three-window LED display for voltage, current, and power with high precision.

Temperature-controlled fan cooling with low noise and long service life. Four potentiometers allow precise adjustment. Binding-post voltage input and convenient selection. Output voltage is continuously adjustable from 0 to the rated voltage. Output current is continuously adjustable from 0 to the rated current. AC input. Three-digit display resolution: 0.1 V / 0.01 A. Four-digit display resolution: 0.01 V / 0.001 A. NPS-W series models include NPS306W, NPS3010W, NPS605W, and NPS1203W. The housing is available in black and white. This series is a miniature switching DC power supply. Output voltage and current can each be controlled and adjusted using variable resistors. The panel includes a high-precision, three-window digital display for voltage, current, and power, allowing users to view the current operating status and various machine parameters.
