MEAN WELL TKA30 series: Isolated triple-output DC-DC converter - TKA30B-B

Description

TKA30B-B — Isolated triple-output DC-DC converter

MEAN WELL TKA30B-B is an isolated triple-output DC-DC converter accepting 18–36 V DC. It provides +5 V and ±12 V DC relative to the Common return, with 25 W total rated output power. The specified current range is 700–3500 mA on +5 V; 62–310 mA on each auxiliary rail; maintain the minimum loads and the combined power limit. Its 2 × 2 inch metal package provides 1.5 kV DC input-to-output isolation. Remote ON/OFF control is provided.

Model and output specifications

Complete model TKA30B-B
Model selection TKA30 identifies the triple-output series. Input code B selects 18–36 V DC. Output code B selects +5 V and ±12 V DC.
Output voltage +5 V and ±12 V DC relative to Common. The +5 V main output and positive and negative auxiliary outputs are all present on this model.
Output current range 700–3500 mA on +5 V; 62–310 mA on each auxiliary rail. Maintain the stated minimum current on each output.
Rated power and load limit 25 W total across all three output rails. Observe every rail current limit and the combined output-power limit together.
Voltage accuracy ±2.0% on +5 V; ±5.0% on the auxiliary outputs.
Line regulation The datasheet lists ±0.5% and ±1.0% line-regulation values, measured from low to high input at rated load. Confirm the applicable value for this model and output rail with MEAN WELL before using it as a design limit.
Load regulation ±2.0% on +5 V and ±5.0% on the auxiliary outputs, measured over 20–100% of rated load.
Ripple and noise 100 mVp-p maximum, measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors.
