GBK is the series designation used for BK control transformers manufactured by GBL. Select the exact model, capacity, voltage and winding configuration to suit the application.

Product dimensions, mounting dimensions and weight data for BKC transformers cover BKC-25VA through BKC-300VA. Contact sales to confirm other specifications.

Dimensional and weight data for QZB three-phase autotransformers covers the listed QZB-22KW to QZB-400KW models. Confirm capacity units and selection against the exact model.

JBK control transformers supply control power for machine tools, mechanical equipment, local lighting and indication circuits at AC 50–60 Hz and up to 1000 V.

JBK5 control transformers use their own dimensional source covering JBK5-40VA through JBK5-5000VA; JBK3 data is not substituted.

SBK / SG three-phase dry-type transformers use air cooling for three-phase voltage conversion in 50 Hz circuits below 1000 V and continuous-duty operation. Capacity, voltage combination and subseries are selected by model.

JMB lighting control transformers provide low-voltage control and lighting power for machine tools, equipment, local lighting and indication circuits; input and output voltages are confirmed per order.

Formal BOD toroidal transformer data covers AC 3–450 V input/output, listed ratings of 20–6000 VA, mechanical dimensions and two mounting methods.

Available R-type transformer data covers mechanical dimensions and listed capacity bands from R-8 to R-5000. Voltage, frequency and other electrical performance remain subject to exact documentation.

DB power transformers are presented against the EI dimensional and weight table from DB-1W to DB-100W, with hole spacing and lead length checked by exact model.

Available TDGC2 contact voltage regulator data covers product dimensions and weights from TDGC2-0.2KVA to TDGC2-15KVA. Similar model names are not merged into this family.

SBW three-phase automatic compensation voltage stabilizer models, product dimensions, package dimensions and weights are confirmed from SBW-30KVA to SBW-2000KVA. Electrical performance is not inferred from the dimensional sheet.

SJW three-phase independently regulated automatic AC voltage stabilizer product dimensions, package dimensions and weights are confirmed from SJW-15KVA to SJW-120KVA. Other electrical data is not inferred.

The input and output reactor family combines ACL input reactors and OCL output reactors for the respective mains and motor sides of variable-frequency drives. Selection data, voltage drop and application position are confirmed separately for each subseries.

CKSG three-phase low-voltage series reactors are used in reactive-power compensation circuits to suppress selected harmonics, limit capacitor inrush current and coordinate with compensation capacitors by system voltage and reactor rate.

GBL-I15, GBL-I25 and GBL-I50 are Type 1 surge protective device series for primary protection at power incomers. Each model is presented with its own catalogue specifications without cross-model extrapolation.

GBL power surge protection covers the GBL-20, GBL-40, GBL-60, GBL-80, GBL-100 and GBL-120 models. Enclosure dimensions depend on model group and pole count; electrical data follows the corresponding type-test report and exact model.

GBL-SCB Surge Backup Protector product series. Contact sales or engineering to confirm the required specification.

TPS160815 Fire Monitoring Temperature Sensor product series. Contact sales or engineering to confirm the required specification.

The GBL-JK family contains the confirmed GBL-JK1 and GBL-JK3 combined electrical fire monitoring detectors. GBL-JK3 works with residual-current transformers and temperature sensors; it is not itself a current transformer.

Fire Monitoring Current Transformer Family product series. Contact sales or engineering to confirm the required specification.

This family presents hosts for two distinct systems: GBL-JKZ for electrical fire monitoring and GBL-XBZ for fire equipment power monitoring. Their monitored targets, detectors and specifications are listed separately and are not interchangeable.

GBL-XBS is a voltage/current signal sensor (fire equipment power monitoring detector) that collects fire-equipment power status and reports it to the monitoring host; it is not the system host.
