The scope of use

Ambient temperature: -40—85℃

Liquid temperature: -40—85℃

Liquid type: Commercial coolants can be used with water pumps, but mixing different coolants is not allowed. The mixing ratio of water and antifreeze is selected in a range of 50/50 to 40/60.

In order for the cooling system to be completely filled with media, the cooling system must be completely drained to a vacuum.

Installation: Vibration and noise requirements must be taken into account in the definition of the installation location and specific fixing elements/fasteners in the application, and the installation position must avoid water accumulation on the surface/inside the connection system.

Typical applications: Energy storage thermal management system, liquid-cooled charging cabinet, data center system

I/O control port

1. PWM. PWM input frequency: 100-1000Hz (200Hz recommended), PWM amplitude: 10-48V, duty cycle speed regulation range description: 0%-10%: pump stop (7% is recommended to stop signal), 11%-55%: pump minimum speed operation; 56%-90%: linear speed range, 91%-100%: maximum speed operation of the pump
2. Fault. Fault feedback signal output (current type): high level (48V) for normal operation, low level (<1V) for fault, and the typical operating current for fault feedback is 5mA
3. GND. Signal GND
4. VSP. Analog voltage input speed regulation(0-10V)
5. 10V. 10V supply.
