Product Description

LTP Series High voltage Power Supply Model: LTP-220VAC-(N/P)400W-20KV
Power range: 400W Voltage range: 0 ~ 20KV Current range: 0 ~ 20mA Portable benchtop chassis Precise voltage and current setting and measurement capabilities OVP, OCP, short circuit and load discharging protections etc.
Overview
LTP series is high voltage power supply designed for high voltage experimental test needs with single-phase 220Vac±10% input. Its maximum output power can reach 1000W and the maximum output voltage can reach 40kV, it is featured for stable & accurate output and low output ripple. Comparing with the traditional linear HV power supply, its high-frequency switching technology can achieve faster response rate and higher efficiency with smaller size and light weight. It is a best choice for HV laboratory testing, product testing and other HV applications.
Features
CV/CC working modes. Output voltage & current adjustable from 0 to 100% Stable & Low ripple HV output. 4-digit LED digital meters display. Perfect & Complete protection functions Compact structure, small size and light weight.
Optional functions
High output precision up to 0.1% (+0.1%) 0 ~ 10V analog signal control (standard DB interface) (+AC) RS communication interface (RS232 / RS485 optional) (+RC)

Protection & Monitoring functions	Load discharging protection		When the load has discharging due to insufficient safety distance between load and ground, the power supply shutdown the high voltage output, and then restarts, so cycle like this till the discharging fault is eliminated.
	Short circuit protection		When a short circuit occurs between the load and the ground, the power supply works in constant current mode, the current is limited to the maximum value, and the voltage drops to 0 to protect the internal inverter from damage.
	Over current protection		When the users' load exceeds the rated load and cause over-loading, the power supply works in constant current mode, the power supply output current does not change, and output voltage decreases.
	Over voltage protection		When the power supply is unloaded, the power supply works in constant voltage mode to prevent power supply from overvoltage damage.
