What is the Martindale PSUPD230 Proving Unit Power Supply?
The Martindale PSUPD230 is a mains-powered 12V DC power supply designed for compatible Martindale proving units. It provides electricians with an alternative to powering compatible proving devices from their internal batteries.
Mains Power for Compatible Martindale Proving Units
The PSUPD230 connects a compatible proving unit to mains power through its external 12V DC power connection. Martindale documentation identifies it for compatible proving units including the PD430, PD440, PD690 and PD700.
How does the PSUPD230 stand out in everyday use?
For regular bench or workshop use, the PSUPD230 provides a convenient mains-powered alternative to relying on proving-unit batteries. When connected to compatible units, inserting the external power jack disconnects the internal batteries.
