The HT-814X is a photoelectric coupler from Hengtuo Technology Co., LTD., designed with two light-emitting diodes and a phototransistor. It offers high input-output isolation voltage (5,000Vrms) and a wide operating temperature range from -55 to 110. Available in a 4-pin package with wide-lead spacing and SMD options, this coupler features AC input response and a minimum Current Transfer Ratio (CTR) of 20%. It holds multiple safety approvals, including UL 1577, VDE DIN EN60747-5-5, and CQC11-471543-2022, and is RoHS and MSL1 compliant. The HT-814X is suitable for applications such as programmable controllers, switching power supplies, intelligent meters, and various home appliances like air conditioners, fans, and water heaters.
