HYDRAULIC POWER UNIT CONTROLLER
HPU Controller by Val Controls
What is a Hydraulic Power Unit (HPU) Controller?
The HPU feature can control a hydraulic pump to keep the pressure in the system within a specified range by monitoring the pressure in the system.
By monitoring the hydraulic system, the HPU controller will shut down the pump if the temperature of the hydraulic oil is too high or if the level of the hydraulic oil in the tank is too low.
The Hydraulic Power Unit (HPU) control is a built-in software feature for Val Controls Intelligent Hydraulic Positioner (IHP24) and the Intelligent Diagnostics Controller (IDC24). The Controller can be used as a dedicated HPU controller or be combined with Partial Stroke Testing or positioning features.
The controller comes in enclosures fit for all types of environments and industries.
Benefits of Hydraulic Power Unit (HPU) Controller
Low- or high-pressure warnings
Low or high oil limit warnings
Can be used for all types of pumps
Protection of the pump
Live information of pump status
HPU controller can also be used for PST or positioning
Temperature monitoring of the pump
High limit alarm
How does it work?
The HPU Controller comes as standard with the following control and communication options:
- 4-20mA with HART
The HPU Controller is always on auto-mode when in use.
During set-up and troubleshooting it is possible to use the following control modes:
- Always on/off
- Local control panel
Pressure, Temperature & Level Input
The HPU Controller accepts the following signal types:
- 4-20mA - 2-wire sensor
- Switch input
- The HPU is powered through a 24VDC power supply.
- Safety timer avaiable
