Description

This chapter briefly introduces the YL4012 precision programmable current source. YL4012 precision program-controlled current source is designed and manufactured by Beijing Yiliang Technology Co., Ltd. It is used for 0-100mA/0-100V (YL4012-100), 0-200mA/0-50V
(YL4012-50) and 0—1A/0—10V (YL4012-10) are high-precision intelligent instruments that provide stable DC current and DC clamp voltage protection for various sample loads, and have the following basic features. […]

Features:

• Clamp voltage accuracy better than ±1% of set value
• 4-wire current output and return voltage output
• The Output button on the front panel is convenient for changing samples when starting up
• When the output is disabled, the two ends of the load are short-circuited to prevent the load sample from being damaged by static electricity
• When the power is off, both ends of the load are short-circuited to avoid power-on impact and electrostatic damage to the load sample
• Optional output compensation network to reduce output noise and suitable for strong inductive loads
• The current range of 4-20mA industrial interface is in the same range, which improves the detection rate of industrial applications
• Output oscillation detection and audible alarm
• 2×16 character dot matrix liquid crystal display
• Good interactive keyboard operation
• Serial computer interface
• Natural air cooling to avoid running noise

Precision programmable current sources can be implemented using specialized integrated circuits (ICs) or through discrete components. Several semiconductor manufacturers, such as Texas Instruments, Analog Devices, Maxim Integrated, and Linear Technology (now part of Analog Devices), offer precision current source ICs that are specifically designed for these applications. These ICs often provide additional features like temperature compensation, multiple channel outputs, and advanced diagnostic capabilities.
