LZSA Series 

## 500-1500W Industrial Power supplies 

https://product.tdk.com/en/power/lzsa www.emea.lambda.tdk.com/lzsa 

The LZSA series offers a unique feature set not commonly found with standard off-the-shelf supplies. Compliance to the MIL-STD-810E standards for shock and vibration and board coating make the LZSA power supplies ideal for use in a variety of harsh environment applications. They also comply with the tough ring wave lightning surge test per IEEE C62.41.  Features include remote on/off, remote sense, frequency synchronization and a wide operating temperature range of -40°C to +71°C.  The series also has a wide adjustment range which can be programmed using an external voltage or resistance. 

|**Features**|**Benefits**|
|---|---|
|• Rugged Mechanical Design With Coating on PCBs|• High Reliability in Harsh Environments|
|• Superior Thermal Design|• Long Life Even at 71°C Operation|
|• Wide Range, Programmable Output Adjustment|• Reduces The Need For custom Outputs|
|• Input Voltage Transient Protection|• Reduced System Filtering|
