The Tektronix PS505 is a 3.0–5.5 V, 4 A power supply plug-in for the TM500 system.
It is designed to operate in the right-hand (high power) compartment of a TM504 or TM506.
In a low-power compartment, a rear switch limits the output to 1 A (indicated by front-panel "NON FLOATING / 1 A LIMIT" LED).
Key Specifications
| Output voltage | 3.0 V to 5.5 V DC, floating (only if operated in a high-power compartment) |
|---|---|
| Output current | 4 A (must be limited to 1 A in a low-power compartment); foldback limit from 4.1 A to 1.5 A (latching) |
| Overvoltage protection | 7 V |
| Line regulation | ±10 mV for 10% line voltage change |
| Load regulation | ±5 mV for 0.5 to 4 A load current change, 20 μs transient recovery |
| Stability and drift | 0.1% + 5 mV drift in 8 hours; max. 0.01%/°C |
