Adjustable high- and low-voltage DC power supply.
DP901 is an adjustable DC supply with separate high- and low-voltage outputs for EV component testing. Each output has its own controls and protection.

Key benefits
HV output
Adjustable 50–900 V DC, up to 5 A.
LV output
Adjustable 0–50 V DC, up to 15 A.
Separate protection
Protection against output faults and short circuit.
Workshop functions
High-voltage output
Adjust 50–900 V DC and up to 5 A for compatible tests, using separate current and voltage controls.
Low-voltage output
An independent 0–50 V DC, up to 15 A output supplies lower-voltage components separately.
Independent circuits
Separate HV and LV modules have dedicated controls and protection circuits, avoiding interaction between output settings.
Connected control
The reference lists Bluetooth control with compatible ST13, P01 and P03 terminals.
Protective circuits
Protection covers short circuit, current limiting, high/low voltage, temperature and reverse polarity.
