The HT2400 product line, which includes HT2420, HT2432, HT2436, HT2464 and HT24120, is a programmable DC power supply family that features high accuracy, high stability and low noise with single channel output.

In terms of over voltage/current protection (OVP/OCP), the HT2400 rapidly detects a problem by utilizing a combination of software configuration and hardware detection, which ensures connected objects against damages if any problem occurs.

Features:
1. Stable output regulation with low noise and high precision 
2. High resolution of output capabilities: Voltage= 1 mV. Current= 100uA. 

3. High resolution of read-back capabilities: Voltage= 1 mV Current= 1uA 

4. Remote Sense compensation 

5. Front panel and rear panel output terminals 

6. Back lighted 20x2 LCD display 

7. Over-voltage and over-current protection 

8. Short circuit and reverse polarity Protection 

9. Intelligent Fan control 

10. Auto Run mode and delay time setting functions 

11. Ramp output function 

12. 100 configurable and recallable states in the memory 

13. ON/OFF control at the output terminal 

14. Standard RS-232C and USB interfaces Optional GPIB(IEEE-488.2) interface
