1. Use purpose

LH42095 circuit is a precision voltage stabilized negative power supply especially designed for operations under high temperature and wide temperature environment, this power supply has the characteristics that output doesn’t change as the input voltage, load current and environment temperature, without connection with the external filter capacitance, the output noise is less than 1mV, and can operate reliably for long term period under shell temperature of 200℃ . It is suitable for all kinds of positive stabilized power supply, especially for electronic equipment under high temperature and wide temperature operation environment and voltage regulation factor and load regulation are smaller compared with foreign products of the same model.

1. Characteristics:

• Output current: 1.5A
• Input voltage to -40V
• Internal limited current protection
• Storage temperature: +200℃
• Maximum output voltage: -30VDC

1. Absolute maximum rated values

• Output current: 1.5A
• Input voltage: -40V
• Working temperature(shell temperature): +200℃
• Storage temperature: -65℃~+200℃
• Power: 25W

1. Model

The company can provide with power supply of output voltage of -1.8VDC~30VDC under operating conditions as required by users. It is s ested to use copper or aluminum for radiator, the device surface should be in close contact with a large area of the radiator and the contact surface is required to be smooth and clean. In addition, it is better for the upper and lower surface of device radiating at the same time and using heat conduction agent.
