How Much Does MKS PDR900 Cost in 2026?

Used units of the MKS PDR900 Digital Power Supply & Readout trade between $728–$1,500 in 2026, while refurbished units range from $1,800–$3,560. Savings vs. new OEM list price (which is ~$12,000–$15,000) are 50–70%. Units with >40,000 RF-hours are preferred, as those with fewer hours may indicate premature replacement or lack of usage. Note that 2026 pricing reflects a 15–20% decline from 2025, driven by surplus inventory and extended lead times for sourcing. Buyers should verify the unit’s calibration certificate and RF-hour count before purchase. Condition-grade B units typically show no major functional issues but may have minor wear, such as cracked housing or degraded connectors. Prices are volatile due to limited availability and growing demand from legacy semiconductor equipment rebuilds.

Specifications and Compatible Tools

The MKS PDR900 provides 900W of power with a voltage range of 0–100V and a current range of 0–10A. It operates at 50–60Hz and includes a digital readout for real-time monitoring. Compatible tools include the MKS PDR900-100 (2015–2018), MKS PDR900-200 (2016–2020), and MKS PDR900-300 (2019–2022). These models integrate seamlessly with older vacuum pumps and process controllers. Avoid units paired with the MKS PDR900-500, as this part number is incompatible due to mismatched control protocols. Always confirm the tool’s firmware version matches the PDR900’s hardware revision (e.g., Rev 3.2 for 2018–2020 models).
